Abstract

Space optical remote sensors are widely used in the field of space to earth and space to sky target observation and detection, and to obtain important information. With the progress of the times and the improvement of scientific research level, space remote sensor has higher and higher requirements for positioning accuracy. In order to improve the positioning accuracy of space remote sensor, it is the most direct and effective way to improve the visual axis stability of the remote sensor. As the space remote sensor system becomes more and more complex, the traditional iterative design method of recalculating the optic axis stability of optical components is less and less desirable. The decomposition of optic axis stability index has become an important basis for optical component design. In this paper, using linear optics theory, taking a space remote sensor as an example, the visual axis sensitivity matrix of the optical system of space remote sensor is obtained by using CODEV, and the overall visual axis stability index of space remote sensor is decomposed into each optical component by using Monte Carlo method. On this basis, the maximum translational displacement and maximum angular displacement of each optical component are calculated. The temperature control index requirements of each optical component are given. This method can provide a reference for the decomposition of the visual axis stability index at the beginning of the design of complex space remote sensor, and further provide a reference for the requirements of the system thermal index, micro-vibration and moisture analysis index.
