一、原理机的结构及其性能红外热成像仪是一种将红外像转变成可见像的装置。图1为我们所研制的红外热成像原理机。其结构分为两部分:(1)摄像机部分其作用是扫描目标源,将其辐射能汇聚在探测器上并转变成电信号。所以摄像机部分由扫描、汇聚光学系统及红外探测器组成。汇聚光学系统为球面反射镜。在扫描光学系统中,帧扫系统为平面镜物面扫 First, the principle of the structure and performance of the machine Infrared thermal imager is a kind of infrared images into a visible image of the device. Figure 1 shows the infrared thermography machine we developed. Its structure is divided into two parts: (1) The camera part of its role is to scan the source of the target, the radiation energy can be gathered in the detector and transformed into electrical signals. So the camera part is composed of scanning, converging optical system and infrared detector. The converging optical system is a spherical mirror. In the scanning optics, the frame sweep system is a planar mirror sweep
