| 中文摘要:集成斯特林制冷式红外焦平面探测器组件具有体积小、功耗低、可靠性高等特点，被广泛应用于各种红外整机系统。其中远程导弹武器系统对制导作战启动时间提出较高要求，现有红外焦平面探测器满足度低。本文通过分析影响红外焦平面探测器的启动时间因素，提出了一种新的设计思路，即通过微型杜瓦、制冷机及其驱动控制器设计，在保证探测器芯片原始性能及探测器光、机、电接口不变情况下，实现快速启动。实验结果表明常温下新设计探测器降温时间在3分30秒以内，相比传统方法，启动时间大幅缩短，满足了项目所需，为红外焦平面探测器在导弹武器系统应用提供新方案。 |

| Abstract:The integrated Stirling-cooled infrared focal plane graphics component has the characteristics of small size, low power consumption, and high reliability, and is widely recognized in various infrared complete systems. However, existing detectors hardly satisfy the strict startup-time requirements of long-range missile weapon systems for guidance-based combat. This article analyzes the factors that affect the startup time of infrared focal plane detectors and proposes a new design concept. By designing a micro - Dewar and a refrigerator drive controller while keeping the original detector’s performance and the optical, mechanical, and electrical interfaces unchanged, rapid startup is achieved. Experimental results indicate that, under this condition, a considerable reduction in cool - down time has been obtained. The cool - down time can be reduced to within 3 minutes and 30 seconds at normal temperature. This significantly improves the detector’s fast cool-down capability and meets the project requirements. |
