Research on the Encoding Method of Single Ring Absolute Code Disc

A new encoding method, which was single ring absolute encoding mode,was put forward by studying the encoding principle of traditional absolute code disc.Based on the designed digit of code disc, the codes that correspond to angle positions were obtained by using VC to program. The pattern was simple and the photolithography technology was easy. The precision of encoder was improved easily and the type of encoder can be made miniature lightly, whose core component is the code disc with the pattern. The method overcame the disadvantage of traditional code disc patterns such as more tracks, complex configuration, difficult photolithography and low encoding precision, and provides theories and technologies of encoding to develop further single ring absolute encoder.
