摘要
本文从理论上深入地分析光折变晶体中简并两波混频的动态特性。通过有关公式的推导,阐明动态两波混频在实时干涉测量中应用的原理。文中还提出利用LiNbO_3:Fe晶体的测量光路,给出其实测结果。并对测量精度作出分析。
Dynamic characteristics of degenerate two-ware mixing (TWM) in photorefra-otive media are theoritically analyzed. The applied principle of TWM in realtime interferometry is disscussed with deduced formula. The optical arrangement for experiment by using LiNbO3:Fe crystal is presented. Some experimental results are given.
