人体是一极佳的热辐射源,其两侧部位的体温具有对称性。当身体某一部位有病变,就可因血流供应及新陈代谢的改变而破坏了这种对称性,并可通过接触病变部位的方法得以感知。如用温度计,热敏电阻、热电偶、半导体温度计等进行测量,但在测温精度方面还不够高,同时还存在接触病变部位(人体)等弊病,此外,总伴有热负载,而使测温不准,重复性差,不能测出各区域的温度分布等问题。用光学-机械扫描测量红外辐射显示人体表面温度分布状况的热成象装置,成功地解决了上述问题。75年我所与昆明211
The human body is an excellent source of thermal radiation with symmetrical body temperatures on both sides of the body. When there is a lesion in one part of the body, this symmetry can be ruined by changes in blood supply and metabolism, and it can be sensed by touching the lesion. Such as the use of thermometers, thermistors, thermocouples, semiconductor thermometers and other measurements, but in the temperature measurement accuracy is not high enough, but also there is contact with the lesion (human body) and other ills, in addition, the total heat load, leaving the test Temperature is not accurate, poor repeatability, can not measure the temperature distribution in various regions and other issues. Thermal imaging devices that measure the temperature distribution on the surface of the human body by means of optical-mechanical scanning of infrared radiation have successfully solved the above problems. 75 years I and Kunming 211
