圆光栅测角系统误差分析与修正

为了提高测角系统的测量精度，基于误差的特性和表现形式，从谐波角度对测角系统中的刻划误差、光电信号误差、偏心误差、倾斜误差和变形导致的误差建立相应的数学模型，并对偏心误差和倾斜误差进行仿真分析。搭建了金属圆光栅测角系统，对系统中的误差进行了分析和修正。实验结果表明：测角系统测角误差为134.2″，修正后误差为32.23″，圆光栅测角系统误差分析为后续的误差补偿提供了理论基础。

Abstract

In order to improve the measurement accuracy of the angle measuring system, based on the characteristics and form of the error, the corresponding mathematical models of the scoring error, photoelectric signal error, eccentricity error, tilt error and the error caused by the deformation in the angle measuring system were established from the harmonic angle aspect,and the eccentricity error and tilt error were analyzed. Furthermore,a metal circular grating angle measuring system was built, and the error in the system was analyzed and corrected. The experimental results show that the angle measurement error of the angle measuring system is 134.2″, and the corrected error is 32.23″. The error analysis of the circular grating angle measurement system provides a theoretical basis for the subsequent error compensation.
