Paper Abstract

The measuring technique of focus shift is adopted in the automatic precision positioner developed by the authors based on the principle of astigmatism. According to the specific result measured a control circuit and a high-precision actuator are designed for the moving-positioning of the positioner. The positioner has been used successfully in a focusing system of an optical instrument. Key words : astigmatism focus shift position detection precision displacing mechanism
