In order to minimize the size of photoelectric encoder, a signal process system was designed and C8051F021 MCU was its core device. To begin with, the processing electrocircuit and the data processing software used for the 16-bit encoder was developed. Then the feasibility of this system was verified by experiment. The experimental result proves that the signal process system was simple in structure and reliable. The size of the electrocircuit was Φ40mm.The precision of the 16-bit photoelectric encoder is 22.4".
