摘　　要：分析并设计了一种新型的光学偏转加速装置,可以对入射光束偏转角度进行倍数放大.该装置利用曲面反射原理,当入射光束发生很小的原始偏转时,其反射光束随之发生偏转且其偏转角度被放大.可通过调节曲面反射镜的曲率来实现微小光学偏转角度放大1～2个数量级.该种技术主要用于非管扫描相机,比如转镜相机、电光晶体偏转相机及其他光学扫描器件,无机械装置,更适合小角度的电光偏转以及古斯-汉欣位移等光学偏转加速.To get more precise high-speed streak cameras,we analyze a novel optical-deflection accelerating technique for light-beam. When the incident light-beam is deflected with a tiny initial deflection angle,according to the law of curved surface reflection,the reflective light-beam is deflected therewith and the deflection angle is enlarged.The deflecting amplification accelerating device can amplify the small deflecting angle by one to two orders of magnitude through adjust the curvature of the curved-surface. This device dominates the optical information capacity in tubeless streak camera,such as rotating mirror cameras,electro-optic crystal deflector cameras,and other light-beam scanning devices. Because there is no mechanical moving part in the new-developed device,this technique is suitable for cooperating with electro-optical deflection and the Goos-Hnchen displacement.
