关键词	Considering that the requirement of industrial manufacture An AT89S51 singlechip works as the core processor of the system. By two laser triangulation a small thickness measurement system based on PSD and FPGA is presented. It takes S3931 PSD of one dimension as position detection device A FPGA produces logic control signals for the whole system the small displacement is converted to differential voltages which is made by Hamamatsu in Japan and after amplification and A/D transformation 8-bit parallel data is send to singlechip from FPGA by external interrupts and the final calculation results output to the LCD display module. After digital micro meter calibration we get the small thickness. Experiments show that the detection accuracy of the system is not less than 10um.
