声—光偏转光学系统主要包含了一个声—光偏转器,声一光偏转器基于声与光相互作用原理,有部分光偏离主光束,其偏离角度与作用的声波频率成正比。由于这一特性,使声—光偏转光学系统广泛应用在大屏幕显示,计算机输出,激光记录技术等很多领域。前年,我们应西北电讯工程学院的要求,设计制造了一种声—光偏转光学系统,用于该院研制的声—光电子侦察接收机,并且取得了良好的效果。本文将着重介绍声— The acousto-optic deflecting optical system mainly includes an acousto-optic deflector. Based on the principle of sound and light interaction, the acousto-optic deflecting device deviates from the main beam by some of the light, and the deviation angle is proportional to the acoustical frequency of the action. Because of this feature, the acousto-optic deflection optical system is widely used in many fields such as large-screen display, computer output and laser recording technology. Two years ago, at the request of Northwestern Telecommunication Engineering Institute, we designed and manufactured an acousto-optic deflecting optical system for the acousto-optoelectronic reconnaissance receiver developed by the institute and achieved good results. This article will focus on the introduction of sound -
