一种高性能的红外像机现在已能按用户的技术规范进行生产。它的基础是电荷耦合器件(CCD)和美国无线电公司十多年来的研究成果。像机的焦平面成像列阵甚至可感知极微量的热,从而可使它看见从几公里以外逼近的车辆,观察人的活动,跟踪热辐射物体或者提供出地形测量数据。 A high-performance infrared camera is now available to users’ specifications. It is based on more than a decade of research done by charge coupled devices (CCDs) and the U.S. radio company. The focal plane imaging array of the camera can even sense a slight amount of heat, allowing it to see vehicles approaching from a few kilometers away, observing human activity, tracking thermal radiation objects, or providing topographic measurements.
