Basler dart BCON
For example, if you are operating a camera with a hardware trigger signal period of 20 ms
(= 0.02 s), the frame rate is 50 fps:
For more information about determining the maximum allowed frame rate, see Section 9.7 on
Two exposure modes are available for hardware triggering:
timed
and
trigger width
.
Timed Exposure Mode
When timed exposure mode is selected, the exposure time for each frame acquisition is determined
by the value of the camera’s ExposureTime parameter.
If the camera is set for
rising edge
triggering, the exposure time starts when the ExFSTrig signal rises.
falling edge
triggering, the exposure time starts when the ExFSTrig signal falls.
illustrates timed exposure with the camera set for rising edge triggering.
When adjusting the settings, make sure not to exceed the maximum allowed
frame rate. If the maximum allowed frame rate is exceeded, the behavior of the
camera can be undefined.
