| 摘 要： | 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。

| Abstract: | The phase-comparison test by means of filling up pulses introduced in this paper is a new method of computer applied in dynamic measuring circular grating. Because the digittal value is directly used in data sampling and processing, two problems, the errors from scaling by hand operation, and the lost of high frequency components in the analog signals, are resolved. |
