Abstract

With the rapid development of space optical technology, the demand for the sensitivity of the optical system has increased, and the corresponding requirements for the suppression ability of stray light has become more critical. As an important part of the optical system to suppress stray light, the suppression effect of the baffle affects the final imaging quality of the entire optical system, and is currently developing in the direction of diversification, high efficiency, and light miniaturization. This paper elaborates the principles and application scenarios of various structural types of baffle, and analyses their applicability and limitations. According to the characteristics of various lens shield structures, they are divided into classical structure, reflective type, deployable type, honeycomb type and venetian blind type, and the characteristics and application fields of various structural forms of baffle are introduced. The research progress of light shields in recent years was introduced from the aspects of structural characteristics, suppression capacity, and application scenarios, and the advantages and disadvantages of various structures and the direction of improvement were discussed. Finally, the development direction of different structural forms of light shields is prospected.
