s
Light is sent from an illumination source inside the SureSight through a beam
splitter and focuses on the back of the eye (retina). The retina, in turn, reflects
the light back into the device. Inside the unit, the beam travels through a series
of mirrors and is received by a micro-lens array, creating an image which is sent
to a CCD camera. The spot pattern of light formed is translated into sphere,
cylinder, and axis.

VISION SCREENER OPTICAL SYSTEM ARCHITECTURE
The following is a description of the present design architecture. A collimated beam of light is projected out
of the patient port by the illumination system. The light is ‘focused” by the eye lens and cornea to a small
spot on the retina. This blur acts as a point source on the back of the eye which then radiates back through
the eye lens and cornea producing a reflected beam which includes information about the lens power and
eye aberrations. The resulting return beam is directed by the beam splitter into the measurement path which
is detected by the camera at the end of the path. To achieve alignment, the practitioner views the patient
eye and the alignment guide pattern through the viewing system. The working distance between the output
port of the device and the patient of approximately 40 centimeters. This large working distance provides the
opportunity to improve accuracy in children, as well as being less intimidating to them. It also reduces the
need for fogging in which is used in conventional autorefractors which work at approximately 2cm.
PN 140399 Rev. B

M AJOR SUBSYSTEMS:
Illumination System:
The illumination system generates a laser beam which can be projected into the eye under test.
Because this laser beam radiates in the infrared region - it is not visible without an IR goggle or other IR
detecting device. For repair and calibration purposes, an ITT night vision scope is recommended for any
work which includes the illumination system.
The source of illumination is a 5 mW electrical, 3 mW optical semiconductor laser located on the
laser mini board. This board is attached to the illumination tube which houses the optics needed to collect
the light emitted by the laser and form it into a beam which is projected from the end opposite the laser. The
laser mini board is connected via a 4 position flex cable to the laser drive board which controls the laser
output. The drive system monitors the laser output with a photodiode which is physically built into the laser
diode. The laser drive system controls the laser output to a particular photodiode level which is set by the
DSP board. The DSP controls this setting with a digital pot on the laser drive board according to a
calibration performed at the factory. This beam is transmitted through the beam splitter located near the one
inch port on the front of the unit.
*SAFETY NOTE: While the laser is capable of emitting 3 mW of optical power, only a fraction exits
the illumination tube. Laser levels are controlled to approximately 18 µW, which is well within Class I safety
limits. However, to prevent improper exposure DO NOT look at the bare laser diode.
A properly functioning illumination system produces an approximately collimated beam of light 2mm
in diameter. This beam can be seen using ITT goggles when a piece of white paper is placed in front of an
operating illumination tube. The collimated aspect of the beam can be observed by the lack of change in
size of the beam (spot) regardless of the distance from the front of the tube.
Measurement System:
The measurement system detects the beam reflected from the patients eye back toward the unit.
This beam enters the product through the one inch port on the front of the unit and is reflected down toward
the bottom of the unit by the reflecting side of the beam splitter. This beam passes through a first conjugate
lens, to two measurement mirrors which bend the beam across the bottom of the unit and back up toward
the top where it passes through a second conjugate lens in to the camera/lenslet assembly. The
camera/lenslet assembly consists of the camera board with a lenslet filter mounted to the top of it by a
lenslet housing. When the beam passes through this lenslet and IR filter, a group of spots are created which
represent the optics of the eye from which the beam came.
The camera image is progressively sent to the DSP board for processing. If a sufficient number and
quality of images is detected, the DSP computes and reports a reading of the optical power detected. The
exposure, gain and other settings of the camera are controlled by the DSP board through a serial port and a
digital pot on the camera board. These settings are also set during the factory calibration.
Viewing System:
The purpose of the viewing system is to create a visible image which can be used to align the
product with the patient. Because the laser is invisible, it can not be used for aligning. Instead, the viewing
system produces a visible crosshair target which is aligned so as to be in the same position as the invisible
laser beam at the in-range working distance. In this way, when the practitioner aligns the crosshair with the
patients eye, they are also aligning the laser which is required to make the measurement. It is critical that
the viewing crosshair be aligned to the laser beam at the proper working distance.
The source of illumination for the viewing system is an LED located on the LED mini board. This is a
traditional LED used to backlight a crosshair which is cut into a cup mounted over the LED. This mini board
and cup assembly is mounted to one end of the viewing tube which contains optics required to magnify and
project the crosshair to the patients position 40 cm away. The LED mini board is connected to the laser
drive board through a 4 position flex cable. The actual drive for the LED is on the laser board and is turned
on and off by the DSP using a single control line.

PC B OARD ASSEMBLIES:
DSP Board:
The DSP board includes the microprocessor which controls the operation of the product. It also
contains the software in a flash EEPROM, external RAM, a real time clock with battery, and the decoding
circuitry for the user button presses. In addition, the DSP board “passes” both power and control signals
between boards. All boards are connected to the DSP and all signals and power are redistributed as
needed. In other words - any connections which must be made between boards do so through the DSP
board.
Power Board:
The power board includes two switching systems to generate all voltages required to operate the
product. It includes the charging control circuitry, the low battery circuitry, the distance measurement
circuitry, and the speaker/tone generation circuitry.
Fixation Board:
The fixation board includes the fixation LED array which is flashed to attract the patients attention. It
also includes the jacks for USB/RS232 connection, and the charging port. The drive circuitry for the RS232
and USB is located on this board, as well as the IRDA sensor which communicates with the printer. In the
central section of this board, the ultrasonic sensor is mounted. However, the ultrasonic sensor circuitry is
actually on the power board, it only sits on the fixation board to match the output port of the housing.
One important note: the fixation board must be present for the system to power up. If the power
board does not sense the presence of the charging jack with no plug present (i.e.: not charging), it will not
power up.
Laser Board:
The laser board provides the drive for both the viewing crosshair LED and the laser. The LED is
controlled with a simple on/off control at a set output current. The laser is controlled to a target level
depending on the setting of the digital pot on this board. The pot is settable by the DSP during each startup
of the device. In addition, the laser has an on/off control which is used in addition to the digital pot to insure
that the laser is off when not required for measurement.
Camera Board:
The camera board contains a full chipset for the black and white imager which detects the return
beam for measurement. The camera exposure control is accomplished via a serial port on the board, and
the gain is controlled by a digital pot which is settable by the DSP. The camera gain is subject to calibration
at the factory.
LCD:
The LCD is a custom assembly of glass and printed circuit board. In addition to a series of seven
segment displays to present the reading results, and various indicators to indicate other conditions, this
board includes the button inputs, and the dip switch inputs. Theses are passed to the DSP for detection and
decoding.
Laser Mini:
The laser mini is a board which is primarily a mechanical mount. The board includes only the laser
diode and a flex connector which mates it to the laser drive board via a flex cable.
LED Mini:
The LED mini is a board which is primarily a mechanical mount. The board includes only the LED
and a flex connector which mates it to the laser drive board via a flex cable.

Notes:
Due to the large variation in parameters which determine the refractive values, (sphere/cylinder
variation from lens value, distance to wheel, exact alignment to lens center, unaccounted for
aberrations in lenses, ND power variation, retinal material variation, fake eye actual
dimensions, etc) deterministic methods do not yield expected values with an acceptable
degree of accuracy. Consequently, boundaries require correlation to positive clinical
performance, and are not deductively linked to the lens value placed in the wheel position.
To revise or reset boundaries if tester or wheel are changed, there are two possible means. Five
or more units can be tested five times to determine range of values, and then clinically
verified to provide proper performance. Since this is very time consuming, the alternative is
to test 30 units under the current settings and then use them to reset and or reverify the
acceptable range of values under the new setup. During this comparison, standard deviations
of the new setup must be sufficiently low so as to allow new boundaries to be set. For
reference, a current set of wheel values including standard deviations is included in the wheel
verification Aspec listed on the BOM.

GENERAL___________________________________________
The purpose of this specification is to provide the product requirements for alignment
for the SureSight product. The process aspec is derived based on these specifications,
and the actual magnification and camera selected for use in the alignment station
tooling. In addition, a specification for the manufacturing setting is listed in addition to
the final product requirement. In each case, the manufacturing specification is tighter
than the final product specification. This is to insure that the manufacturing setting plus
the repeatability variation do not exceed the final product requirement. It should be
noted that if the final product requirement is used for the manufacturing setting limits excessive fallout would be likely at the final tester due to variations in repeatability.
Unless otherwise specified:
• Fake eyes to be built as per Fake Eye Construction Aspec on BOM. Nominally this
includes a 4.5mm pupil. (ref)
• All measurements to be completed at nominal working distance = 360mm from first
conjugate surface to front surface of fake eye.
1. MAXIMUM GLARE
All alignments to be done with fake eye positioned for maximum glare. Maximum glare
occurs when the laser is projected into a fake eye in the center and perpendicular to the
lens. This demonstrated by achieving the brightest glare within the image. In general,
this will also occur roughly in the center of the return image. See Figure 1.

2. BEAM SPLITTER/CAMERA ALIGNMENT
The purpose of the beam splitter alignment is to place the return image in the center of
the camera active area. This insures that the margin of aiming is as equal as possible
in the up, down, right, and left directions. For example, if the beam splitter image is
aligned toward the top of the camera active area, any slight aiming above this will drop
the image off the camera - resulting in no readings.
To facilitate measurement of the image position, a green box function is projected by
the software in the exact center of the camera active area, and in a size which
represents the 4.5mm image. For reference, the camera active area is 696 by 494
pixels. The green box is 300 by 300 pixels, and positioned with a center of 348,247 to
correspond with the center of the active area.
Image position accuracy is measured in number of lines outside the green box. Given
the pitch of the lenslet, each line outside the box corresponds to 1mm of offset in the
position of the center of the image compared to the center of the camera active area.

Row Measurement
The measurement of rows outside the box on any side is as follows:
Only rows which are three or more spots are considered a row.
If the row sits on the green line, it is counted as a half row.
If the row is fully outside the line, it is counted as a full row.
Figures 2 shows some examples of row counts.

The purpose of the mirror alignment is to place the crosshair image on top of the laser
at the nominal working distance. This insures that the when the physician aligns the
crosshair with the patients pupil, he is also aligning the laser to the pupil. This is
necessary because the laser is not visible and can not be aligned without an alternate
means.
As noted below, the alignment station setting specification is .41 mm from the pixel
center. This is to insure that it will meet the crosshair product specification of .76mm
from the center of the pupil. When unit is initially shipped to the field, Repair Stations
are allowed a modest increase beyond this to cover plate to plate variation which is 1-2
pixels (typical).
For convenience, crosshair position accuracy can be measured in pixels from pupil
center. The equivalent specifications in pixels for the alignment station as well as for
the final tester are listed below.
The acceptable limit for the number of pixels the crosshair center can be from the pupil
center is a function of the magnification of the optics as well as the resolution of the
observing camera. Any alteration of camera or magnification would require revision to
these specifications. The procedure for determining the magnification as well as the
number of pixels within the product specification is listed in the next section.

4. MAGNIFICATION MEASUREMENT
The purpose of the magnification measurement is to determine the pixels per millimeter
of a particular optical/camera setting. This magnification is multiplied by the
specification in millimeters to convert to specifications in pixels for that station.
Procedure:
1. Place a metric ruler as close to the plane of the fake eye pupil as possible and
placed across the pupil so that the numerical labels on the ruler can be seen for at
least 30 mm. The ruler tick marks should be clearly visible and the ruler should be
as straight as possible.
2. Using FPGEYE software, grab a picture of the ruler and save the image.
3. Open the image using Vision Builder, PC Paint or equivalent.
4. Count the number of pixels which are visible over a 30mm span of the ruler.
5. Compute this number/30 to determine pixels per mm magnification.

GENERAL______________________________________
These revision logs are maintained for reference, and do not contain every single
change which has been made to this product. It is intended to provide a list of major
changes which are relevant to the repair and troubleshooting of units. Any critical
product traceability should be done through the Welch Allyn ECR documentation.
Unless otherwise specified:
• All changes refer to both eyecare and primary care units. S/N’s for each model are
given in the S/N log.
• S/N’s and Dates refer to best estimate of implementation. Units which are very
close to this transition may or may not have been run to the new change and should
be checked for compliance. An estimate of 2 weeks, or 20 units would be an
expected potential overlap.
• It is the judgment of the ECR originator through the ECR process to determine if a
change merits inclusion on this list. Changes may also be added after the ECR as
long as the relevant dates and S/N’s are supplied.
• Changes are noted under each category that they impact. Most will occur in at least
two categories.
