Study of Grating Signal Processing Based on FPGA

Abstract:

With the development of modern measurement and control technology,the grating sensor is widely used in the measurement of displacement and angle in precise meterage domain. Limited by the grating scratching technology,the way to improve the measurement precision of grating sensor is using electronic technique to subdivision the grating signal. This paper mainly research on raster displacement detection system based on FPGA. As the usual raster sensor data collection system has many problem,A new raster sensor data collection system was found based on FPGA &USB. In this system,FPGA was used as main controller , and the USB was used for data transmission. A whole system hardware circuit design was given in this paper, including the FPGA processing of the raster sensor signal, and the USB circuit design
