美国在开展星球大战计划的过程中投入大量的人力财力开发——项关键项目——焦平面阵。这是一种在60年代和70年代夜视仪基础上发展起来的可在夜间、浓雾和稠密云层背景下使用的灵敏度很高的红外探测成象系统。与以往的红外探测器相比,其优点是视野宽、灵敏度高、体积小,采用无源传感技术,可通过吸收红外频谱的光得到成象 The United States devoted a great deal of manpower and resources development during the Star Wars project - a key project - the focal plane array. This is a highly sensitive infrared detection imaging system developed on the basis of the 60’s and 70’s night vision devices for use in the background at night, in dense fog and in dense clouds. Compared with the previous infrared detector, its advantages are wide field of view, high sensitivity, small size, the use of passive sensing technology, by absorbing the infrared spectrum of light to be imaged
