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.

A novel visual tracking algorithm to cope with occlusion and scale variation is proposed. This method combines mean shift and SIFT algorithm to track object. SIFT algorithm is invariant to rotation  translation and scale variation. But it is a timeconsuming algorithm. The wasting time is related to image size. So the proposed algorithm first adopts mean shift to initially locate object position  then SIFT operator is used to detect features in object area and model area  lastly  the proposed method matches features in these two areas and calculates the relationship between them using affine transform. According to affine transform parameters  the state of object can be adjusted in time. In order to reduce process time  an improved feature matching algorithm is proposed in this paper. Experiments show that the proposed algorithm deals with occlusion successfully and can adjust object size in time. 2008 IEEE.
