提出采用猫眼逆向反射器 (CER)作为 He- Ne激光器的运动腔镜 ,取代平凹腔的平面反射镜 ,以降低其对导轨直线性要求 ,提高该系统作为频率分裂位移传感器的量程。用矩阵方程讨论了各种 CER的特性 ,给出相关理论分析和实验结果。
Propose cat eye retroreflector (CER) as a moving cavity mirror of He-Ne laser and a planar reflecting mirror instead of a flat cavity to reduce its linearity requirements on the guide rail and improve the system’s range as the frequency splitting displacement sensor. The matrix equation is used to discuss the characteristics of various CERs, and the related theoretical analysis and experimental results are given.
