HWX型医用热象仪是由中国科学院上海技术物理研究所、上海第二医学院、上海市纺织工业局第二医院、上海市第六人民医院和上海注射器三厂以及其它一些单位和个人联合研制而成的。现将该仪器的工作原理和结构,作一较详细的介绍。一、仪器的物理基础红外辐射就是通常所说的红外线或红外光,它是一种电磁波。红外辐射的波长通常认为大约在0.72～1000μm之间。从应用角度出发常常分成近(0.72～1.5μm)、中(1.5～20μm)、远(20～1000μm)三个红外波段。红外辐射的强度(即光谱分布)和温度有
HWX-type medical thermometer by the Chinese Academy of Sciences, Shanghai Institute of Technical Physics, Shanghai Second Medical College, the Second Hospital of Shanghai Textile Industry Bureau, Shanghai Sixth People’s Hospital and Shanghai Syringe Factory No. 3 and some other units and individuals jointly developed Made of Now the working principle of the instrument and structure, make a more detailed introduction. First, the physical basis of the instrument Infrared radiation is commonly referred to as infrared or infrared light, it is an electromagnetic wave. The wavelength of infrared radiation is usually thought to be between about 0.72 and 1000 μm. From the application point of view is often divided into nearly (0.72 ~ 1.5μm), medium (1.5 ~ 20μm), far (20 ~ 1000μm) three infrared bands. The intensity of infrared radiation (ie spectral distribution) and temperature are
