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.

In order to make photoelectric encoder usable in a spaceflight camera which adopts CAN bus as the communication method  CAN bus interface of the photoelectric encoder is designed in this paper. CAN bus interface hardware circuit of photoelectric encoder consists of CAN bus controller SJA 1000  CAN bus transceiver TJA1050 and singlechip. CAN bus interface controlling software program is completed in C language. A ten-meter shield twisted pair line is used as the transmission medium in the spaceflight camera  and speed rate is 600kbps.The experiments show that: the photoelectric encoder with CAN bus interface which has the advantages of more reliability  real-time  transfer rate and transfer distance overcomes communication line's shortcomings of classical photoelectric encoder system. The system works well in automatic measuring and controlling system. 2009 SPIE.
