If the camera enables the line trigger, you can select Encoder Module Out as trigger source. At this
time, the camera will receive signal A and signal B with phase difference. After internal computing,
the outputted signal can be used as camera’s trigger signal. The function demonstration of shaft
encoder module is shown below.

The advantages of shaft encoder are as follows:

Encoder output pulse frequency is proportional to rotating speed.

The output pulse acts as a trigger signal for line scan camera.

Synchronize acquisition speed and sample movement of camera.

Non-uniform motion can also be a perfect match.

A trigger signal can be set as acquiring multiple lines or multiple frames with adjustable ratio.
