A TWO-DIMENSIONAL IMAGE STABILIZATION STAGE DRIVEN BY PIEZOELECTRIC ACTUATORS

摘要：

Optical image stabilization system occupy an important place in infrared imaging products.Piezoelectric actuators have great advantages such as high-response and high-precision.A 2D stage using linear piezoelectric actuators is designed to achieve image stabilization.The piezoelectric linear actuator contains a shrinkage amplification mechanism and a stretching amplification mechanism,which can provide large stroke for the stage.Experimental results show the actuator has 67 μm displacements under the sine voltage of 120 V and the displacement is proportional to the voltage,the change of frequency has little effect on the displacement under the low frequency.It proves that the design scheme is feasible and provides a basis for integrated stabilization institution.
