Abstract
An approach named Windowed XOR photography is proposed for optical readout bimaterial cantilever focal plane array (FPA) imaging. It can replace the conventional differential amplifying method for separating the target from the background radiation. Compared with the conventional method, the approach is helpful to reducing image data's bit-width for processing, avoids negative values and data overflow. A novel integrated aspheric optical readout system and digital processing system were developed to evaluate the approach. Comparative infrared imaging experiments were conducted. The results and analyses show that the Windowed XOR photography has preferable effect and performance.
