Abstract:

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°C 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.

Key words: uncooled IRFPA camera, uncooled micro-bolometer, colorimetric temperature measurement, temperature control network
