Area Scan Cameras

The set up of a frame grabber chain running an area scan camera is straight forward. As mentioned in the previous section the camera must be set into triggered mode. Also the master frame grabber must be set into triggered mode. The microEnable IV frame grabber allows two different trigger modes:

  1. In grabber controlled mode microEnable IV triggers the camera with a periodical signal. Both, period and exposure time, are controlled by software. It does not need any external trigger source.
  2. In triggered mode the frame grabber generates a single pulse on each (rising or falling) edge of an external source (i.e. a light bulb or a generator). The exposure time of this signal is set by software.

All other frame grabbers in the chain - the slaves - can be set to free run mode (however, every mode will work).
