摘　　要：光栅自动测试仪是对直线透射式光栅的精确度实现自动测试的仪器。通过对光栅自动测试仪的基本测试原理进行分析,给出了测试仪的总体设计方案。介绍了在光栅自动测试仪的实现中所用到的关键技术,即高速数据采集和数据存储技术以及步进电机的细分驱动技术。经过设计和调试,成功地实现了光栅自动测试仪。A grating auto testing instrument is to realize auto testing to the precision of linear grating. By analyzing the principle of grating auto testing, a general design of the instrument was given. Then, the key technologies in the realization of the testing instrument were introduced particularly thatare data collection and data store in highspeed and microstep driver. Design and examination, the design requirements was reached, and a grating auto testing instrument was realized.
