    • An uncooled infrared sensor can be used for a plurality of applications such as fire fighting, surveilling a border or any desired area, and limb sounding. The uncooled infrared sensor includes manually or automatically adjustable optics that receive an electromagnetic signal, focus the electromagnetic signal and provide a focused electromagnetic signal to a focal plane array. The focal plane array includes a plurality of detector devices disposed in rows and columns to form the focal plane array. Each detector device is constructed so as to have a reduced pitch and provide a maximum number of detectors within a minimum square area of the focal plane array. Each detector device detects the focused electromagnetic signal incident upon it, converts the focused electromagnetic signal into a sensed signal and outputs the sensed signal so that the focal plane array provides a plurality of sensed signals. The sensor also includes a focal plane array processor that has a plurality of cells corresponding to the plurality of detector devices. The focal plane array processor receives the plurality of sensed signals, processes the plurality of sensed signals to correct for any gain and any offset errors between the plurality of sensed signals due to any inconsistencies between any of the detector devices of the focal plane array and any inconsistencies within the cells of the focal plane array processor itself, and outputs a plurality of processed signals. The sensor also includes a display processor that receives the plurality of processed signals and converts the plurality of processed signals into a video signal suitable for display. The focal plane array processor, the display processor and a controller also provide temperature stabilization of the sensor, manual or automatic calibration of the sensor, manual or automatic gain and level control of the sensor and automatic or manual calibration of the sensor.

    • Techniques that eliminate or otherwise reduce retroreflections associated with focal plane arrays (cooled and uncooled) and other tilted devices are disclosed. The device topology is designed so that incoming radiation is reflected outside of the incoming focusing optical cone. Planarization is used to eliminate concave geometries and angled sidewalls can be used to eliminate convex geometries, as such geometries cause retroreflection. The resultant structure is covered with reflective material (e.g., aluminum, titanium tungsten, or other standard metallization), which not only safely reflects light from the scene, but also prevents reflections from the underlying geometries of the via. Devices configured in accordance with the principles of the present invention require less tilt, thereby minimizing optical distortion.
    • 公开了消除或以其他方式减少与焦平面阵列(冷却和非冷却)和其它倾斜装置相关联的后向反射的技术。 器件拓扑结构被设计成使得入射辐射被反射到入射聚焦光锥的外部。 平面化用于消除凹面几何形状,并且成角度的侧壁可用于消除凸几何形状,因为这些几何形状会导致回射。 所得到的结构被反射材料(例如,铝,钛钨或其他标准金属化物)覆盖,其不仅安全地反射来自场景的光,而且防止来自通孔的基本几何的反射。 根据本发明的原理构造的装置需要较少的倾斜,从而最小化光学失真。
