Abstract
A method for verifying alignment of image sensors of a CCD camera, the method including casting a collimated light source through an LCOS controlled to be disposed in a first pattern, onto the image sensors to form a second pattern on each of the image sensors, the LCOS disposed between a collimated light source and the CCD camera, frame-differencing the first pattern with the second pattern of each of the image sensors to result in a differencing result for each of the image sensors, and adjusting at least one of an orientation and a position of one of the image sensors if the differencing result for the one of the image sensors is non-zero, to result in an optical mapping of pixel cells of the LCOS and pixel cells of each of the image sensors.
