Exposure Modes in Detail
Mode 2: Internally Programmable Line Rate and Exposure Time
Mode 2 operates at a user specified line rate and exposure time.
•
When setting the line rate (using the
ssf
command), exposure time will be reduced,
if necessary, to accommodate the new line rate. The exposure time will always be set
to the maximum time (line period – line transfer time – pixel reset time) for that line
rate when a new line rate requiring reduced exposure time is entered.
•
When setting the exposure time (using the
set
command), line time will be
increased, if necessary, to accommodate the exposure time. Under this condition, the
line time will equal the exposure time + line transfer time.
Example 1: Exposure Time less than Line Period
Mode 3: External Trigger with Maximum Exposure
Line rate is set by the period of the external trigger pulses. The falling edge of the external
trigger marks the beginning of the exposure.
Example 2: Line Rate is set by External Trigger Pulses.
