Calibration Procedure - Teledyne Sapera LT 8.10 Getting Started Manual

Calibration Procedure

• Setup the camera to capture a uniform dark image. Black paper with no illumination and the
camera lens' iris closed to minimum can provide such a black image.
Click on Acquire Black Image. The flat field demo will grab a video frame, analyze the
•
pixel gray level spread, and present the statistics. If acceptable, use the image as the black
reference.
Setup the camera to acquire a uniform white image (but not saturated white). Even
•
illumination on white paper can be used. It is preferable to prepare for the white level
calibration before the calibration procedure.
Click on Acquire Bright Image. The flat field demo will grab a video frame, analyze the
•
pixel gray level spread, and present the statistics. If acceptable, use the image as the white
reference.
Test the calibration by enabling flat field correction during a live grab. If necessary, adjust
•
the dead pixel detection threshold and repeat the calibration.
Save multiple versions of calibration data to compare for best imaging or for different
•
imaging setups.
