摘　　要：本文介绍用阴影、纹影相干涉方法确定等离子体折射系数变化的原理。分析了等离子体中的非线性效应和对光探测系统的基本要求。并简要叙述了实验上采用的后向喇曼探测束,给出了等离子体干涉、纹影和阴影的测量结果。Various nonlinear optical effects in plasma are analysed. The basic requirements of an optical probing system are discussed. Shadow,Schlieren and Interference methods are used to determine the changes of refractive indices of plasma. A brief description of a system of backward Raman scattering presently in use is given. Plasma photographs obtained by the interference, schlieren and shadow methods are given.
