红外焦平面成像技术是一种通过摄取景物热辐射分布，并将其转换为人眼可见图像的技术，广泛应用于侦察、制导、空间探测等方面.针对红外制导小体积、快速启动的应用要求，设计了快速启动红外焦平面成像制导系统.对应用于系统的折反式红外镜头、快速启动型红外焦平面探测器、低噪声成像电路等进行了设计,设计结果满足制导条件下的红外成像要求.

The imaging technology of Infrared focal plane array(FPA) detector is a method which converts the thermal radiation of the target into the visible image. It is widely used in target seeking, missile guidance and space exploration, etc. For the requirements of small volume and fast cool-down application in missile guidance, an infrared FPA imaging guidance system was designed, including the catadioptric infrared lens, fast cool-down IRFPA detector, and low noise image circuit. The whole system satisfies the imaging requirements of the missile guidance.
