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

According to Generic Reliability Assurance Requirements for Passive Optical Components GR-1221-CORE (Issue 2
January 1999)
reliability determination test of different kinds of passive optical components which using in uncontrolled environments is taken. The test condition of High Temperature Storage Test (Dry Test) and Damp Test is in below sheet. Except for humidity condition
all is same. In order to save test time and cost
after a sires of contrast tests
the replacement of Dry Heat is discussed. Controlling the Failure mechanism of dry heat and damp heat of passive optical components
the contrast test of dry heat and damp heat for passive optical components (include DWDM
CWDM
Coupler
Isolator
mini Isolator) is taken. The test result of isolator is listed. Telcordia test not only test the reliability of the passive optical components
but also test the patience of the experimenter. The cost of Telcordia test in money
manpower and material resources
especially in time is heavy burden for the company. After a series of tests
we can find that Damp heat could factually test the reliability of passive optical components
and equipment manufacturer in accord with component manufacture could omit the dry heat test if damp heat test is taken first and passed.
