Abstract
in order to realize the purpose of grating electronic subdivision, using a microcomputer calculation method of interpolation. The method is based on single chip real time on the sine and cosine of two grating more fringe signal acquisition and calculation, according to the calculated results to determine the phase of the signal that the segmentation point, then that grating displacement. In this paper, application of SCM about algorithm to finish 64 subdivision of grating, and successfully used in research projects, to achieve satisfactory achievements in scientific research. Calculation method of interpolation by single chip microcomputer and has popularization and application value of the conclusion.
