摘　　要：针对传感器安装偏心、使用环境变化等因素造成时栅转台精度降低的问题,提出了由多面棱体和自准直仪对误差进行标定,并利用谐波修正技术进行误差修正的时栅转台自动标定系统。系统以多面棱体和自准直仪高精度测量仪器作为测量基准,以ARM处理器为核心对步进电机进行闭环控制,实现转台的精确定位,且能够进行数据采集和误差处理。经实验证明:与手动标定方式相比,该标定系统不仅效率高而且标定后的时栅转台测量系统分度精度可达±1.3″。Aiming at the problem of time-grating turntable precision reducing induced by sensor mounting eccentric or environmental changes and so on,present automatic calibration system for time-grating turntable which calibrates error by polygons and autocollinator and use harmonic wave correcting technology for error correction.Polygons and autocollinator high-precision measuring instruments are applied to the system as measuring standard,ARM processor is used as core to carry out closed-loop control on stepper motor and achieve precise positioning,and the system can carry out data acquisition and error processing. Experimental result shows that compared with manual mode,the calibration system is not only high efficient,but also indexing precision can reach ± 1. 3＂ after calibration.
