一种红外双波段衍射望远镜的光学设计
An optical design for dual-band infrared diffractive telescope
摘要
Abstract
In this paper, the double-layer harmonic diffractive element ( HDE) structure is investigated and the optimization procedure is based on the equation of diffraction efficiency of the double-layer diffractive optical element. The diffraction efficiency of the system in the designed middle and far infrared wavebands is larger than99％, which improves the image contrast and the imagequality significantly. A newdual-band infrared double-layer HDE telescope is designed, which can work in the middle and far infrared wavebands. It is shown that the system approximately attains diffraction limit and is easy to processed.关键词
