光折变自适应光外差探测系统中的自激分析

Analysis of self-excitation in the photo refractive adaptive optical heterodyne detection system

首先说明光折变自适应光外差探测系统中的自激振荡现象，然后利用已有的关于光折变自适应光外差探测系统的理论分析结果和Ｂｏｇｏｄａｅｖ等人对双相位共轭镜中扇开光的处理方法，给出系统中自激振荡问题的定量分析．

The self-excitation phenomenon in the photorefractive adaptivc optical heterodyne detec-tion system(PAOHDS)is describcd.By use of the method with which Bogodaev et al.dealtwith the fanning light in a double pliaseconjugate mirror,we have made a theoretical analysisof this problem on the basis of the discussion on PAOHDS we have made recently.
