基于STM32的时栅转台高精度自动标定系统设计
摘要
针对目前时栅转台采用手动方式进行标定
工作效率低、精度难以保证的现状
设计了一种能够进行数据采集、处理和误差补偿的时栅转台自动标定系统。该系统以激光干涉仪作为测量基准
采用了闭环控制技术
进行测量误差补偿。实验结果表明:该系统标定精度高
经过该系统标定后的时栅转台精度达到±2″
且标定速度是手动方式的2倍以上
显著提高了时栅转台标定效率。
Abstract
Aiming at present state of low efficiency and precision is hard to guarantee in the process of manual calibration of time-grating turntable
an automatic calibration system with which can carry out data acquisition
processing
and error compensation for time-grating turntable is designed.Closed-loop control technology measurement error compensation
the system takes laser interferometer as measurement standard.Experimental result shows that the turntable precision can reach ± 2″ after calibration and the calibrating speed is twice more faster than manual mode
the calibration efficiency of time-grating turntable is significantly improved.
