中文摘要	variable curvature mirror (vcm) is a simplified active optical component being capable of changing its curvature radius. curvature radius variation within a wide range requires that the vcm should be able to generate a large saggitus variation. besides that, the surface form accuracy should be maintained above a reasonable level. in this paper, a piezoelectric actuation based prototype vcm is designed, constructed and experimentally tested. the thickness of the k9 plane mirror is only 3mm over the full aperture of 100mm. six piezoelectric actuators are fixed into a base plate and the head of each actuator is connected to an annular ring through the screw thread. with such a structure, the force provided by each actuator can be transformed to the mirror backside through this annular ring. with each actuator generating the same force, the curvature radius can be changed in a uniform way. at the mean time, the surface form accuracy could be adjusted one point by point to compensation asymmetric modes as well. mathematical analysis and fea (finite element analysis) are used together to demonstrate the theoretical correctness. besides that, the prototype vcm is successfully constructed and experiments have been carried out to give a quantitative assessment on the saggitus variation..
