Abstract

For the earth observation system, new designed optical imaging systems are generally based on pushbroom image. With the development of infrared array detectors, this technology, which gives consideration to both spatial resolution and radiative sensitivity, is extended to infrared instruments. But increase of the field of view(FOV) drops the off-axis image quality and drops the resolution of the system. The structure using array aperture in synthesized manner makes it possible to increase both image quality and radiative sensitivity.
