本文介绍的填脉冲比相法是应用计算机技术进行圆光栅动态检测的一种新方法。由于直接用数字量进行采样和数据处理,因此解决了以前用模拟信号进行采样所产生的高频成分损失和人工定标误差这两个问题。
This paper describes the pulse-by-pulse phase method is the application of computer technology for circular grating dynamic detection of a new method. Due to the direct digital sampling and data processing, thus solving the two problems of the loss of high-frequency components and manual calibration error caused by the analog signal sampling.
