Non-Overlap
Mode
Non-Overlap mode allows you to expose the array for the exposure time specified in the
software and is similar in performance to a normal, full-frame device. The operational sequence
for this mode is:
1. Clearing the CCD,
2. Exposing for the specified exposure time,
3. Shifting the image from the sensor area to the frame-transfer area, and
4. Reading out the CCD.
Steps 1-4 are repeated for each frame in a sequence. Steps 1 and 3, clearing the CCD and shifting
the image, are usually very short and typically have minimum impact on the frame rate.
Figure 7. Non-overlap Mode Operational Sequence
In PVCAM compatible software, this sequence is programmed by simply setting:
• clocking mode to “Frame transfer” and
• clearing mode to “Pre-exposure” with clear count of “1”(or more).
Figure 8 shows these settings on a software dialogue box.
Note: Since the software you are using may show the settings differently, you should refer to the software
documentation for accurate information.
