At present, the demand for infrared detection is increasing, in order to reduce noise, an infrared optical system needs to be imaged in a low-temperature environment, and the infrared luminescence technology is rapidly developed. The heat conduction between the optical system and the external environment is one of the key factors for restricting the development of the infrared luminescence technology. How to effectively block the conduction of external heat to the optical-mechanical system is a key to ensure the temperature stability of the optical element.
For a low-temperature infrared cooling optical system, the internal optical-mechanical system is complex in structure, and strict requirements are put on the overall temperature stability and uniformity of the optical-mechanical system in order to ensure the imaging quality of the low-temperature infrared cooling optical system. Typically, the actual working environment of the optical-mechanical system is 100K or even lower, while the testing and experimental processes are performed in room temperature environment, and the temperature change is more than 180K. The low-temperature infrared luminescence system is usually installed inside the vacuum cabin, the optical mechanical system is cooled in the vacuum environment to reach the required low-temperature environment, and external heat is always transferred into the system along the joint of the low-temperature optical mechanical system and the vacuum cabin.
At present, heat insulation materials are mainly adopted for low-temperature infrared luminescence systems at home and abroad to realize heat insulation. The heat insulation supporting structure is made of invar steel materials, the rigidity is good, the heat conductivity coefficient is low, however, the problem of overlarge weight caused by the high density characteristic of invar steel is difficult to solve in a space remote sensing system with high light weight requirement; the other type is a heat insulation structure made of glass fiber reinforced plastic, polyimide and other heat insulation materials, and has light weight and low heat conductivity coefficient, but the brittleness and low rigidity performance of the heat insulation structure cannot meet the mechanical property of the support structure. The problems of the optical-mechanical system and external heat conduction cannot be effectively prevented by the scheme.
