Phase Overlapping in Area-Scan

Area-scan phase overlapping is allowed when the following conditions are met:

MultiCam parameter

Value

Description

Expose

PLSTRG

WIDTH

The area-scan camera feeding the channel operates in the "asynchronous reset" modality

Readout

INTCTL

ALLOW

It is possible to trigger the optical image capture while the previous image is read out of the camera, as shown in the following drawing:

TE is a shortcut for Trigger Event. In this particular case, TE represents the frame trigger pulse.

The waiting phase duration is set by the adjust-level MultiCam parameter Expose_us.

Thanks to the phase overlapping feature, the theoretical maximum frame rate, usually only feasible is the "synchronous scanning" modality, can be reached in asynchronous reset applications.

This allows for the highest frame rate in "on-the-fly" grabbing acquisition.
