概述用红外热象仪高精度测温时,大多需外配温度标准。例如,国内已进口了瑞典AGA公司各种型号的红外热象仪几十台,如要求测温精度较高时,可配该公司的1010型温度参考源。这种参考源是一种温度设定范围从16～100℃,温度设定精度为±0.2℃,表面发射率为0.97的便携式面状辐射源。售价较高,而且进口的数量很少。为与我所研制的HWRX-1型红外热象仪(或其他热象仪)配套,我们已研制出与AGA1010性能相似的一种便携式红外温度参考源——DHD-1型红外温度定标源(以下简称定标源),其外形见图1。
Overview With infrared thermometer high-precision temperature measurement, most with the temperature standard. For example, the company has imported dozens of various types of infrared thermal imagers from Sweden AGA Company. If the temperature measurement accuracy is high, it can be equipped with the company’s Model 1010 temperature reference source. This reference source is a portable, planar radiation source with a temperature setting range of 16 to 100 ° C, a temperature setting accuracy of ± 0.2 ° C and a surface emissivity of 0.97. Higher prices, and the small number of imports. For supporting the HWRX-1 infrared camera (or other thermal imager) developed by our company, we have developed a portable infrared temperature reference source similar to the AGA1010, the DHD-1 infrared temperature calibration source (Hereinafter referred to calibration source), its appearance shown in Figure 1.
