Application progress of optical system used for soft x-ray detector

Data from soft X-ray telescope can provide the basis for revealing some extreme physical laws and phenomenon. So, X-ray telescope is a kind of important equipment for space science observation. Soft X-ray optical system is the core component of X-ray telescope system, and according to its influence on X-ray, the optical system is divided into three categorys: collimating type, focusing type and modulating type. By introducing the working principle, performance characteristics, preparation technology and application status of the three optical system at home and abroad.The three important development trends about the space X-ray detection load technology is made: optical system miniaturization and lightweight; easily of array integration; multi-dimensional information of X ray photon is extracted. This analysis will give powerful guide for design of the soft X-ray optical detector in the future.
