General Description
®
The DynaVision L1 sensor is a high performance line profiling sensor which can be
used in a wide variety of applications including the profiling of logs, boards, and other
diffuse, or nearly diffuse, surfaces. The L1 sensor is particularly suited to the profiling
of long extruded shapes.
There are currently three models of L1 sensor s available. They are distinguished by
their measurement region and y-axis sampling resolution:
L1-16-20-24:
This is the "standard" L1 sensor. It has a
measurement region extending from 16”to
36”and a 24" field of view (FOV) at 36"
(equivalent to an angular field of view of
36°). Its y-axis sampling resolution is 1/8".
L1-16-6-15:
This is a higher resolution L1 sensor with a
reduced operating range.
It has a
measurement region extending from 16”to
22”and a 15" FOV at 22" (equivalent to an
angular field of view of 39°). Its y-axis
sampling resolution is 1/16".
L1-16-20-15:
This is an intermediate version of the L1
sensor.
It has a measurement region
extending from 16”to 36”and a 15" FOV at
36" (equivalent to an angular field of view
of 22°). Its y-axis sampling resolution is
1/16".
Multiple L1 sensor s can be combined to measure larger objects that exceed the field of
view (FOV) of a single sensor . An array of L1 sensor s can be used to surround
objects and provide complete three-dimensional (3D) scans.
The L1 sensor is assembled entirely from solid-state components housed in a rugged,
sealed enclosure. Range measurement makes use of the latest laser triangulation
technology by projecting a laser line onto the surface of the object being measured.
The CCD array housed in the sensor detects the laser energy reflected from the object.
The sensor incorporates a processor per head approach to data processing using
high-speed, embedded computers.
