传统的非接触性测温系统主要采用红外CCD,其工作波长大多为0.4～1.1 μm,受到截止波长的 影响,红外CCD在工业中低温测量误差过大。非制冷焦平面红外热像仪(uncooled IRFPA camera)的工作波 长一般在8～14 μm之间,常温环境下测温可精确到0.01℃。UL01011型非制冷微测辐射热计是非 制冷焦平面热像仪中最常使用的核心光电探测器,以此作为实验用光电探测器件,构建了非接触性工业测 温系统,从实验结果可以看出,该方法在实际应用中获得了较好的效果。

In the aspect of infrared detector, the operating wavelength of the traditional infrared CCD is 0.4～1.1 μm. Affected by the cut-off wavelength, the error of infrared CCD is very large in industrial low temperature measurement. The operating wavelength of uncooled infrared focal plane array (IRFPA) camera is generally between 8～14 μm, of which temperature measurement accuracy can reach to 0.01℃ under the optimum working environment. The UL01011, most commonly used as the core photo detector in the uncooled focal plane uncooled micro-bolometer array infrared camera, was used as the experimental photoelectric detector. Experimental results showed that this method can achieve better results in practice.
