Camera Performance and Features
Exposure Mode Sequential
Relevant Features: ExposureMode, ExposureTime, ExposureDelay, TriggerDelay, OutputDelay,
OutputDuration
Unique to the Linea ML camera is the sequential exposure mode. For each trigger entering the
camera the exposure for each line can be executed separately and in a serial sequence. This allows
the user to set up different lighting conditions for each line. The figure below shows a typical time
case for exposure mode sequential:
Figure 14Typical Sequential Timing
The trigger signal entering the camera is routed to the sensor and also to each of the output
control features.
The TriggerDelay feature delays the trigger going to the sensor. This delay allows the user to turn
on the LED before exposing the sensor.
Each line can be delayed relative to the previous line using the ExposureDelay feature.
Note: The ExposureDelay feature can only be applied to the second, third or fourth lines being
exposed.
The exposures for each line cannot overlap.
