Abstract

This paper presents a new method in the application of computer in fine dividing grating signals the basic idea of which is to use computer software in the analysis and processing of measured results of grating signals to generate a fast look-up table. The round sum of grating signals'' preiods is counted by a hardware-counter and the fine dividing value is processed by means of software . The whole system consists of simple circuits but has a high accuracy and a high resolution ratio. Key words: fine dividing grating interference fast look-up table sinusoid constant-amplitude orthogonality.
