The CCD plane of the space tridimensional mapping camera will be deviated from the focal plane(including the CCD plane deviated due to camera focal length changed)  under the condition of space environment and vibration  impact when satellite is launching  image resolution ratio will be descended because defocusing. For tridimensional mapping camera  principal point position and focal length variation of the camera affect positioning accuracy of ground target  conventional solution is under the condition of vacuum and focusing range  calibrate the position of CCD plane with code of photoelectric encoder  when the camera defocusing in orbit  the magnitude and direction of defocusing amount are obtained by photoelectric encoder  then the focusing mechanism driven by step motor to compensate defocusing amount of the CCD plane. For tridimensional mapping camera  under the condition of space environment and vibration  impact when satellite is launching  if the camera focal length changes  above focusing method has been meaningless. Thus  the measuring and focusing method was put forward based on astigmation  a quadrant detector was adopted to measure the astigmation caused by the deviation of the CCD plane  refer to calibrated relation between the CCD plane poison and the asrigmation  the deviation vector of the CCD plane can be obtained. This method includes all factors caused deviation of the CCD plane  experimental results show that the focusing resolution of mapping camera focusing mechanism based on astigmatic method can reach 0.25 m. 2010 Copyright SPIE - The International Society for Optical Engineering.
