Paper Abstract

Using broadband hybrid diffractive/refractive optical system, an athermalized imaging system without special optical and mechanical materials, which is the prototype for space borne small CCD camera, has been designed, evaluated, fabricated and tested. The comparison with conventional optical system is presented. Also, the paper analyzes and discusses the effect of parasite orders diffraction from binary optical element as the regular `stray light' on the image quality (MTF and contrast), and proposes an approach of image processing that can compensate such image quality degradation when broadband hybrid system is used in CCD camera.
