Analyzing characteristic of the cube-corner retroreflector applied to laser straightness measurement

对角锥棱镜用于激光直线度测量时可使测量精度提高一倍的光学特性进行了分析。分析了角锥棱镜的制造角差、面形误差和测量过程中角锥棱镜的偏摆、俯仰、滚转对直线度测量的影响。用实验验证了分析结果。分析结果为角锥棱镜用作激光直线度测量时的误差分析和误差补偿提供了理论依据。

The optical properties of doubling the measurement accuracy using the cube-corner retroreflector which is applied to laser straightness measurement are analyzed in theory. The effects on straightness measurement are analyzed for the cube-corner retroreflector with angle errors, surface errors, yaw, pitch and roll. The analysis results are proved by experiments. The analysis results indicate that this work has provided the theoretical basis for analyzing error and error compensate during the laser straightness measurement with cube-corner retroreflector.
