To improve the automatic detection efficiency of photoelectric encoder
an auto-detection system of photoelectric encoder is designed using DSP (TMS320F2812) as the core device. A 21-bit high accuracy photoelectric encoder is used as the angle standard. It is connected to the detected photoelectric encoder coaxially. They will rotate synchronously under the driving of electric motor. Data acquisition and processing system collects the angular data of the two photoelectric encoders at the same angular position and calculates the angular error of detected photoelectric encoder. Then the data is put into computer. The computer will display the data error. The result of experiment shows that the system could detect encoder whose bit-number below 19
the detecting person could be reduced to one and the detecting speed could be increased to 8-10 times. 2010 IEEE.

In order to improve the reliability of the Composite Optical Encoder during wide temperature range
we have designed a new code slot of the Composite Optical Encoder with high precision. Firstly we will show the causations which influence the code slot to correct the coarse code. Secondly
we will reckon the range of the coarse code caused by the width of the code slot. Finally
we will design the code slot of the Composite Optical Encoder. It is proved that the new code slot could make the coarse signal steady and reliable during - 40C+60C. That is very important to improve the stabilization and the reliability of the Composite Optical Encoder. 2010 IEEE.
