PHOTOMETRY
This command selects Photometry settings and controls. An application can use
user selected gain and exposure or it can use the auto-photometry algorithm to
determine the correct settings at each trigger.
Syntax
•
Define automatic photometry control. Perform photometry control at each
trigger and prior to each image scan:
PHOTO[METRY] AUTOMATIC [opt2] [opt3] [opt4] [opt5]
Where:
opt2 — Min exposure — The minimum shutter/exposure duration value
used for Auto control. (30 - 100,000 usec)
opt3 — Max exposure — The maximum shutter/exposure duration
value used for Auto control. (Min exp - 100,000 usec)
opt4 — Min Gain — The minimum gain value used for Auto control.
(0 - 1023)
opt5 — Max Gain — The maximum gain value used for Auto control.
(Min Gain - 1023)
•
Define manual photometry control. Do not perform automatic photometry at
each trigger. If opt2 and opt3 are supplied, use these values at each scan.
Each PID can have its own gain and exposure settings:
PHOTO[METRY] MANUAL [opt2] [opt3]
Where:
opt2 — Exposure range (30 - 100,000 usec)
opt3 — Gain (0 - 1023)
