title = "The effect of temperature distribution on reflectors in satellite optical terminals",
abstract = "Considering of orbital environments and working mode of the reflectors, thermal model of the 45-degree reflector assembly in satellite optical terminals on orbit is established to obtain temperature distribution of the reflectors(the extreme low temperature is -38.0°C, the extreme high temperature is 32.2°C and the max temperature gradient is 3.3°C), meanwhile, a thermal-optical vacuum experiment based on the analysis results is conducted to check the effect of temperature distribution on reflectors.the results shows: if temperature of the reflector is ≥-10°C, the reflector shape accuracy PV will be better than λ/3, and the RMS will be better than λ/30 (λ=632.8nm), but it becomes worse and is not able to meet application requirement when the temperature decreases continuously(-40°C ∼-10°C). So it is necessary to design reasonable active heating loops for reflector assembly to guarantee its performance on orbit.",
