红外热成像测温仪原理及其在疫情防控期间的应用

红外热成像技术,即通过检测物体表面的红外辐射,采用二维图像成像的方式直观反映物体表面温度的分布情况,可远距离实现对物体的非接触式测温,具有快速、方便、可靠、准确及数据可实时互传等优势。目前,在新冠肺炎疫情常态化防控期间,新冠肺炎疑似病例的首要筛查依据是人体体温检测,因此,在人流量较多的场所,快速有效的体温检测仍然是新冠肺炎疫情防控的第一道防线。文章从热成像基本原理出发,介绍热成像技术的原理与应用,并结合当前新冠肺炎疫情,介绍热成像测温仪在人员流动较大场所的相关应用。

Infrared thermal imaging technology is the infrared radiation technologyof detecting the object surface using two-dimensional image imaging to directly reflect the surface temperature distribution of the object,which can realize the non-contact temperature measurement of the object over a long distance,with the advantages of quickness,convenience,reliability,and accuracy and real time inter-transmission of data.At present,during the normal prevention and control of COVID-19 epidemic,the primary basis for screening suspected cases of COVID-19 is the detection of human body temperature.Therefore,in places with a large flow of people,rapid and effective body temperature detection is still the first line of defense for COVID-19’s epidemic prevention and control.Based on the basic principle of thermal imaging,this paper introduces the principle and application of thermal imaging technology,and,according to the current epidemic situation of COVID-19,introduces the application of thermal imaging thermometer in places with a large flow of people.
