    • A low cost infrared camera (1) for night vision. The camera (1) is disposed within a housing (2) having an infrared transmissive window (6) disposed at an input aperture (5) thereof. A compact optical arrangement (10) is disposed within the housing (2) to focus energy from the window (5) onto a focal plane array (20). A chopper disk (19) is positioned between the reflective optical arrangement (10) and the focal plane array (20) to establish a reference level for the array (20) and to facilitate a sequential readout thereof. A signal processing circuit (100) is included for processing the output of the array (20) for display on a standard video screen. Thus, the problems with uncooled detectors are overcome by use of a fast optical system in combination with an uncooled detector. The fast optical system provides a high signal level to the uncooled detector, thereby compensating for losses in collection of thermal radiation. Reflective optical systems can be manufactured inexpensively from plastic or aluminum and reduce the need for expensive infrared materials commonly used in military systems. The combination of the fast optics and uncooled detector provides a truly low cost thermal camera for night vision.
    • 低成本的红外摄像机(1)用于夜视。 相机(1)设置在具有布置在其输入孔(5)处的红外透射窗口(6)的壳体(2)内。 紧凑的光学布置(10)设置在壳体(2)内以将来自窗(5)的能量聚焦到焦平面阵列(20)上。 斩波盘(19)定位在反射光学装置(10)和焦平面阵列(20)之间,以建立阵列(20)的基准电平,并便于其顺序读出。 包括信号处理电路(100),用于处理阵列(20)的输出以在标准视频屏幕上显示。 因此,通过使用快速光学系统与非冷却检测器结合来克服非制冷检测器的问题。 快速光学系统为未冷却的检测器提供高信号电平,由此补偿热辐射的收集损失。 反射光学系统可以廉价地从塑料或铝制造,并且减少对军用系统中通常使用的昂贵的红外材料的需要。 快速光学和非冷却检测器的组合为夜视提供了真正低成本的热像仪。
