Paper Abstract

In order to realize laser beam steering, a driving and control system based on Voice Coil Actuator (VCA) is designed for linear motion of micro-lens array. According to the feedback displacement signals acquired from displacement sensor, controller of the system sends control signals to Purse Width Modulator (PWM) driver which is used to power the VCA. VCA provides driving force for the support structure of the system which connects the micro-lens array, and then the linear motion of micro-lens array is achieved with the movement of support structure. The effectiveness of the system was verified through experiment. Experiments results show that the displacement resolution of the linear driving and control system is 10&mgr;m , which satisfies the requirement for laser beam steering.
