摘　　要：测温准确度较低是制约红外测温在精准测温领域应用的重要因素。目前红外测温的主要测量对象是低反射率物体,简称为低反体。针对传统红外装置在低反体精准测温方面的不足,采用反射器替换传统红外装置的镜头制成反射器红外装置,以提高其对低反体的测温性能。计算和测试结果显示,F数为1的红外镜头被替换为反射器后,红外装置对低反体的辐射收集能力和测温准确度提高约4倍。此外,低反体充满视场后,反射器红外装置的温度测量结果与测量距离无关。反射器红外装置有望用于科研和工业领域的高精度红外测温。The low accuracy of temperature measurements is a significant factor that restricts the application of infrared temperature measurements in precise temperature measurement fields.Presently,the primary objects for infrared temperature measurement are those with low reflectivity,referred to as low-reflectivity objects.To address the deficiencies of conventional infrared devices,a reflector infrared device was developed by replacing the lens of a conventional infrared device with a reflector,thereby enhancing its temperature measurement performance on low-reflectivity objects.Calculations and experimental results indicated that,after replacing the F/1 infrared lens with a reflector,the radiation collection capability and temperature measurement accuracy of the infrared device for low-reflectivity objects improved by approximately four times.Furthermore,when the field of view was filled with a low-reflectivity object,the temperature measurement results of the reflector-infrared device were independent of measurement distance.Infrared reflector devices are promising candidates for high-precision infrared temperature measurements in both scientific research and industrial applications.
