The Timing Generator's functions of Scientific Grade CCD Camera is briefly presented: it generates various kinds of impulse sequence for the TDI-CCD  video processor and imaging data output  acting as the synchronous coordinator for time in the CCD imaging unit. The IL-E2TDI-CCD sensor produced by DALSA Co.Ltd. use in the Scientific Grade CCD Camera. Driving schedules of IL-E2 TDI-CCD sensor has been examined in detail  the timing generator has been designed for Scientific Grade CCD Camera. FPGA is chosen as the hardware design platform  schedule generator is described with VHDL. The designed generator has been successfully fulfilled function simulation with EDA software and fitted into XC2VP20-FF1152 (a kind of FPGA products made by XILINX). The experiments indicate that the new method improves the integrated level of the system. The Scientific Grade CCD camera system's high reliability  stability and low power supply are achieved. At the same time  the period of design and experiment is sharply shorted. 2010 Copyright SPIE - The International Society for Optical Engineering.  
Research of active supporting technology based on 400mm thin mirror (EI CONFERENCE) 会议论文

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.
