Paper Abstract

For the earth observation system, most newly-designed optical imaging systems are generally based on the principle of pushbroom imaging. With the rapid development of infrared array detectors, this technology, which gives consideration to both spatial resolution and radiative sensitivity, is extended to instruments with thermal infrared wavebands. Comparing with separate detectors system, the pushbroom imaging system using array detectors possesses a wide field of view (FOV) which reduces the off-axis image quality and is harmful to the resolution of the system. The structure using array aperture in synthesized manner makes it possible to enhance both image quality and radiative sensitivity.
