【Abstract】 According to the demand for absolute zero postion proposed by an incremental encoder,a mathematical model of reference mark pattern has been set up,and the theory of designing the reference mark pattern has been put forward perfectly.A computer aid design program has been made.With this tool,a group of reference mark pattern used in engineering have been designed.The property and designing of the reference mark,and property of absolute zero position signal have been discussed.更多还原
