Using a spherical mirror of 400mm diameter and 12mm thickness  active supporting technology of thin mirror is researched. The axial support of the mirror is composed of 12 active supports and 3 fixed supports. The force actuator  which is composed of displacement actuator and force sensor  is installed in the active support. The mirror surface is tested by Zygo interferometer. For calibration  each actuator exerts unit force alone  and the surface variation is tested and taken as the response function of the actuator. The response functions of all actuators compose the stiffness matrix. Then the stiffness matrix is used by damped least square method to determine the correction force of each active support. In order to analyze the correction capability of the active supports  14 Zernike modes of the mirror surface are generated and tested respectively  and 7 modes are selected for correction. Initially  the RMS error of mirror surface is 1.16 I( =0.6328nm)when all actuators exert the same force. After 5 iterations  the RMS error of mirror surface is reduced to 0.13  close to the original surface quality. 2010 Copyright SPIE - The International Society for Optical Engineering.
