摘　　要：研究了激光陀螺反射镜基片表面粗糙度和波度前、后向散射的测量计算及其对散射的影响。研究结果表明:在同样的精度下,表面粗糙度比波度对散射的影响更大.因此.提高表面粗糙度的精度是降低激光陀螺反射镜或其它超高反射率镜面散射损耗的主要途径。This article introduces the measuring and the calculation of forward and backward scattering in some range of surface roughness and waviness of laser gyro mirror substrate and presents the effect of surface roughness and waviness on scattering. The research results indicate that surface roughness has more effects on scattering than surfare waviness with the same accuracy and improving surface roughness is a main approach to reduce the scattering loss of laser gyro mirror surface or other mirror surface with super-high reflectance.
