Research on Application of Laser Welding to Uncooling Infrared FPA Detector
激光封口在非致冷型红外焦平面组件封装中的应用研究

Compared with a cooled infrared detector, an uncooled infrared detector has the advangtages of small size, low weight and low power consumption because it has not any cooler. To improve the encapsulation process of an uncooled infrared detector after exhaustion and achieve its configuration optimization and reliability enhancement, a technical scheme to use laser welding to encapsulate the uncooled infrared detector in high vacuum is proposed. The test result shows that the uncooled infrared detector assembly has not apparent variation in performance and can meet the requirements for actual application.
