Paper Abstract

The Young's dual-pinhole interference fringe generated by the structure of Mach-Zehnder interferometer was projected to the object. High-speed signal acquisition card based on FPGA and multiple DSP is developed for dynamic use. High-precision and broadband LD controller is also developed. CMOS camera is used in the image acquisition. And the whole optic path of the system uses fiber optic, which helps to realize the fiber optical integration and miniaturization of the system.
