近年来Risley棱镜在**侦察领域得到越来越多的应用。介绍Risley棱镜的基本组成, 从数学模型上论证了Risley棱镜两种工作原理及其应用技术, 分析了工程实现的难点, 描述了国内外的工程应用情况, 国防科技大学研制的物理样机可实现10°光束偏转, 实验结果表明已初步实现了扫描成像和光束扫描功能。

In recent years, the application of Risley prism on the military reconnoiter came to wide attention. The basic configuration and working principle were demonstrated individually, and the troubles on engineering implementation were analyzed. The products at home and abroad were described. The maximal refraction angle of light beam is 10° on Risley prism prototype developed by university of defense technology. Some experiments results show it has realized the scanning imaging function and light beam scanning function preliminarly.
