热象仪是显示红外图象的仪器。任何物体只要它的温度不是绝对零度都具有红外线辐射。在医学上,红外热象仪可以用来测定人体各部位的温度,人体有炎症的部位,其局部温度会略高于周围的平均温度。在实际使用中,测量设备的温度,在30℃时,最小误差达0.2℃。仪器有转镜和振镜组成的横向、纵向扫描机构,能连续扫描摄取人体不同部位的热辐射信息,经会聚由红外检测元
The thermal imager is an instrument that displays infrared images. Any object has infrared radiation as long as its temperature is not absolute zero. In medicine, infrared thermal imager can be used to determine the temperature of various parts of the human body, the site of inflammation of the human body, the local temperature will be slightly higher than the average ambient temperature. In actual use, the temperature of the measuring equipment, at 30 ℃, the minimum error of 0.2 ℃. The instrument has a rotating mirror and galvanometer consisting of horizontal and vertical scanning mechanism that can continuously scan the different parts of the human body to absorb thermal radiation information gathered by the infrared detection element
