摘　　要：光电编码器作为一种角位移测量传感器广泛应用于多个领域中,根据光栅盘的编码方式主要分为绝对式和增量式2种。绝对式光电编码器多用于角度测量,增量式光电编码器多用作速度测量,由于器件的限制,高速、高冲击是增量式光电编码器的1个瓶颈。结合材料的高低温性能和强度特性,采用CPLD硬件细分,设计了1种增量式光电编码器,该种光电编码器具有高速(转速为3 000 r/min)、高冲击性(峰值500 g)、超小型(外径为Φ27 mm,高度为15 mm)和较好的高低温(-40^+70℃)性能等优点。Photoelectric encoder as a sort of angular fields. It is classified into absolute photoelectric lute photoelectric encoder is used to measure the displacement measurement sensor is widely applied in encoder and incremental photoelectric encoder. Mainly, the angular displacement, and the many abso- incremental photoelectric encoder is used to measure the speed. High speed and high impact property is a bottleneck of incremental photoelectric en- coder limited by electronic components. In this paper, FPGA chips are adopted as hardware subdivision, a type of incremental photoelectric encoder is designed based on the high-low temperature performance and strength charac- teristics of used material. The experimental result shows that the incremental photoelectric encoder has many advan- tages ,such as high speed（3 000 r/min） ,high impact properties（ peak value is 500 g） ,super miniature （the diam- eter is 27 ram,the high is 15mm） ,and better high-low temperature performance（ -40 - ＋70℃ ）.
