摘　　要：随着空间遥感技术的快速发展,高分辨率的超大规模拼接类红外探测器的空间应用需求加大。但此类探测器组件的制冷机在工作时扰动明显,这会影响探测器的成像质量,因此需对该扰动进行抑制,以保证探测器组件的在轨工作状态。介绍了一种首次为超大规模红外探测器组件引入自身减振设计结构并验证有效的研究成果。项目根据获得的制冷机扰动测试结果,设计了不同扰动传递路径的隔振结构。通过仿真分析和校核修正,最终完成地面试验验证。该设计可满足探测器组件自身实现超高分辨率扰动抑制的需求。With the rapid development of space remote sensing technology,the demand for space application of high-resolution infrared detectors increases.However,the refrigerator of this type of detector assembly is disturbed obviously during operation,which will affect the imaging quality of the detector.This disturbance needs to be suppressed to ensure the working state of the detector assembly on orbit.A super large-scale infrared detector assembly with a self-damping design structure is firstly introduced,and the effective research results are verified.Based on the obtained refrigerator disturbance test results,vibration isolation structures with different disturbance transmission paths are designed.Through simulation analysis and correction,the ground test verification is finally completed.This design can meet the needs of the detector component to achieve ultra-high-resolution disturbance suppression.
