三、红外探测器的最近发展近十年来,红外探测器的研制工作集中在红外成象器件上。其目标是要制造出其工作性能达到最后极限的焦平面列阵红外探测器。这里包括材料的研究和器件结构的研制以及信息处理电路的研制。下面将先说明现代红外成象对器件的要求,然后介绍几个方面的发展情况。 1.红外成象对探测器件的要求 60年代初期的红外成象系统采用单元红外探测器,利用水平和垂直两个方向的机械扫描,把整个视场中的景物信息逐点采集,然后用与上迷扫描相反的过程将这一维信息,布成二维
Third, the recent development of infrared detectors The past decade, the development of infrared detectors focused on the infrared imaging device. Its goal is to create a focal plane array infrared detector whose working performance reaches the ultimate limit. Here includes material research and device structure development and information processing circuit development. The following will explain the modern infrared imaging of the device requirements, and then introduce several aspects of the development. 1. Infrared imaging of the detection device requirements The early 60s infrared imaging system using a unit of infrared detectors, the use of horizontal and vertical directions of the two mechanical scanning, the entire field of view scene information collected point by point, and then with The process of scanning the opposite of this one-dimensional information, cloth two-dimensional
