Trigger, Reset and Strobe in Area-Scan
In order to ensure the terminology consistency throughout the MultiCam documentation, the following terminology conventions have been taken.
A trigger pulse, or frame trigger pulse, is an electrical signal sent by the external system to instruct a frame grabber to take control over the camera, including exposure control, and to perform a frame acquisition. This is usually used when an asynchronous capture of a moving object is involved. The trigger pulse is issued by a position sensor indicating when the observed object is adequately located in the field of view.
A reset pulse, or frame reset pulse, is an electrical signal sent by the frame grabber to instruct an area-scan camera to start its frame acquisition cycle.
A strobe pulse is an electrical signal sent by the frame grabber to control an external illumination device. The strobe pulse timing is controlled to adequately fit into the frame timing of the area-scan camera.
