Abstract

With the development of space infrared focal plane detectors towards large-scale, multi spectral, and high integration directions, issues such as heat leakage, micro vibration, and structural thermal adaptation have become increasingly prominent, becoming bottlenecks that restrict the application of large-sized infrared focal plane detectors. By using a new Dewar with a string structure, the support problem of infrared focal plane components has been solved. Through the analysis and verification of force thermal coupling design, the new Dewar structure has effectively reduced heat leakage, Reduced the impact of micro vibrations and avoided detector stress caused by thermal adaptation, providing a solution for the application of high-performance large-sized infrared focal planes.
