The thermal control indicators CAE methods of Space optical remote sensor are analyzed in the presented work. We sat up a thermal optical analysis model for space optical remote sensor. By assuming fully covered by in-orbit temperature load
and using the finite element method for thermal deformation analysis
we obtained the optical remote sensor surface deformation and displacement under various thermal loading. Using ZERNIKE polynomial
wave was fitted to obtain ZERNIKE polynomial coefficients which were incorporated into the optical system design. Using CODE V optical calculation software
heat-ray machines under elastic deformation of the system point spread function
transfer function (MTF)
wave front differential (WFE) etc. were calculated. Image quality changes of remote sensors are discussed in variety assumed cases such as temperature loads of quality change. By repeated iteration
critical value of temperature fields meeting the design requirements are obtained for the optical system. Optical indicators were converged to the temperature field indicator
then reasonable indicators of thermal control for remote sensors were obtained. For the thermal control design
this method provided a reliable basis for design. (2011) Trans Tech Publications
