A single-ring absolute optical shaft encodes is designed by studying the encoding principle of traditional absolute optical shaft encoder. A particular description of the orientation arithmetic of the encoder is specified,the signals receiver and hardware design of signals acquisition system are introduced, and effect factors which affect measuring precision of the encoder are analysed. The measuring results show that the encoding method and design of the encoder are correct,which provide theory and examination basis to realize mini-type and intelligent encoder.
