With the progress of infrared technology and detector performance, medium-wave and short-wave infrared technology has been increasingly used in civil, military and aerospace fields because of its better imaging performance in bad weather. As the key module connecting detector array and backward image processing circuit, the readout circuit has important influence on the performance of medium wave and short wave infrared camera system and determines the final image quality. The development status of medium wave and short wave infrared image sensor’s readout circuit is summarized in this paper. The noise, dynamic range, frame rate and other problems are analyzed. And the solutions to the above problems are presented. Finally the future design prospect of readout circuit is also discussed.
