As a complex space optical remote sensor with multiple optical channel and detectors

the optical-mechanical structure and the mounting mode and the load distribution in the spectral imaging apparatus present a asymmetric form. It’s very complex and difficult to practice heat control in the spectral imaging apparatus. CCD component is important element of image-forming system

furthermore

it’s a difficult point at the same time. The degree of thermal design have a direct reference of imaging quality. The characteristics of CCD component heat control in the spectral imaging apparatus are discussed and analysed. The corresponding thermal design scheme of CCD component is introduced and this component is simulated by means of software IDEAS-TMG. The guide line of thermal control is achieved. At last

the thermal design scheme is verified by proof heat test.
