热电摄象管是一种二维实时热成象器件。物体的热辐射用红外成象透镜经调制盘调制,透过锗窗口在靶面上成象,目前我们选用钽酸锂单晶作靶面材料。管子在工作时,信号板导电层维持在同一电位上,因而对应于入射热辐射图样,在靶背面产生相应的电 Thermoelectric tubes are two-dimensional real-time thermal imaging devices. The thermal radiation of the object is modulated by a modulated disk with an infrared imaging lens and imaged on the target surface through a germanium window. At present, we use lithium tantalate single crystal as the target material. When the tube is in operation, the conductive layer of the signal board is maintained at the same potential, so that corresponding to the incident thermal radiation pattern, a corresponding electric power is generated at the back of the target
