Paper Abstract

The phase-comparison Test by means of Filling up Pulses introduced in thig paper is a new method of computer applied in dynamic measuring circular grating. Because the digital value is directly used in data sampling and processing, two problems, the read errors from scaling by hand operation, and the lost of high frequent characteristics in the analog signals, are resolved by this method.
