Designing a System of Interferometry Based on DSP
Interferometry is a meterage technology which is based on light-wave interference theory. In the general interferometry measurements, the procedure of analyzing and studying interferogram depends on a processing system mostly based on PC. In this paper an image processing system based on DSP is conceived, and the entire system consists of a image collecting module, a digital data exchanging interface and a image processing module. A typical interferogram collected from experiments is processed by the system conceived above. Comparing the processed stripe with the ideal pattern, we found that the system is competent for interferometry.
