Paper Abstract

The FPA Infrared imaging technology is widely used in military and civilian fields, and the optical readout FPA Infrared imaging technology is one of the most important branch. How to get a higher sensitivity IR image is very important since there are many factories that can degrade image quality. In this paper we introduce a method to improve system image quality, which is called the holographic compensate illumination based on the holographic technology. Firstly, we analyze the key influencing factors of the image quality of an optical readout FPA IR imaging system, and the two kinds of manufacturing errors of the FPA are given. Then we point out the principle of the method to compensate the FPA fabrication errors and design the experimental scheme. The result of the experiment shows that we can get a more uniform and higher sensitivity IR image by the method of holographic compensate illumination.
