Parameter Description

This parameter establishes the method according to which the illumination control pulse is generated.

For area-scan cameras, the StrobeMode parameter relates to the illumination during the frame exposure period.

The default value is set automatically to MAN or AUTO by the exposure controller of MultiCam.

Equivalent features apply to line-scan cameras.

Description

The strobe function is disabled. No strobe line is allocated to the channel. The hardware line dedicated to issuing the strobe pulse is available for general-purpose usage.

Description

The strobe function is enabled with an automatic timing control feature. The camera exposure and read-out principles, as declared by Expose and Readout , are involved. Two cases are to be considered:
  • The grabber positively controls the camera exposure function, as reflected by Expose = WIDTH for area-scan camera. This is the grabber controlled exposure case. In the grabber controlled exposure case, the parameters StrobeDur and StrobePos are used as specified to define the strobe pulse, using the TrueExp_us duration reported by the grabber.
  • The exposure function depends on camera settings, as reflected by Expose = PLSTRG for area-scan camera. This is the camera controlled exposure case. In the camera controlled exposure case, the strobe pulse starts upon sending the asynchronous reset pulse to the camera, and ends upon receiving the first vertical validation pulse from the camera that indicates beginning of read-out.

Description

The strobe function is enabled with a manual timing control feature. StrobeDur and StrobePos are used as specified to define the strobe pulse, using the TrueExp_us duration. However, the application is requested to write the exposure duration into TrueExp_us beforehand.
