Abstract:The value of HSI(Hyper Spectral Imager)infrared subsystem is introduced.The thermal requirements of the infrared subsystem,such as optics elements,focal plane arrays and geometry structure,are summarized.The characteristics of active and passive thermal control are compared,and the thermal control strategies of HIS infrared subsystem are presented.The thermal control technique for infrared subsystem is also depicted.The radiant cryocooler and the mechanical cryocooler are compared and stirling cooler are briefly stayed.At last the challenges of thermal control for infrared subsystem are put forward.
Keywords:space optics  hyper spectral imager  infrared subsystem  thermal control technique
