红外技术应用日益广泛,新的应用提出了一些新的问题和要求,促进了红外技术的进一步发展。本文从以下几个方面加以介绍。一、红外测温红外测温的特点是非接触、快速和灵敏,但准确度不高。原因是红外测温是通过测量红外辐射推算物体的温度。红外辐射不仅是温度的函数,还是物体表面比辐射率ε的函数,另外还受环境辐射的影响。因此红外测温在高的背景辐射和小的比辐射率的物体为对象应用时特别困难。而现在往往对此很感兴趣。例如:
The application of infrared technology is more and more widely used. New applications have proposed some new problems and requirements, which have promoted the further development of infrared technology. This article is introduced from the following aspects. First, infrared temperature measurement Infrared temperature measurement is non-contact, fast and sensitive, but the accuracy is not high. The reason is that infrared temperature is calculated by measuring the infrared radiation temperature of the object. Infrared radiation is not only a function of temperature, but also a function of the emissivity, ε, of the surface of the object as well as the effects of ambient radiation. Therefore, infrared temperature measurement is particularly difficult for objects with high background radiation and small specific emissivity. And now is often very interested in this. E.g:
