| Abstract: | This article describes a system based on FPGA that using to subdivide the grating signal. It explains the generation process and the basic approach of grating signals,and has come up with a design which integrate the EDA technology and the Moire fringe subdividing technology.It implements the main design of the system through VerilogHDL,and completes the simulation experiment by ISE software. Experiment suggests that the system has many characteristics such as the high tracking speed,high precision,little r... |
