带通红外比色滤波测温技术研究

提出可精确测量中低温物体温度的带通比色滤波测温理论，利用该理论，搭建了相应的实验装置。对装置所用的器件进行精确标定，并利用数值函数对测试得到的离散点数据拟合后，用面源黑体在５０℃～４００℃范围对该实验装置进行了测温实验验证，实验结果表明，该实验装置在不需知道目标发射率的情况下，能精确测量物体的真实温度，因此，验证了提出理论的正确性与所建立测温系统的可行性，对中低温物体真实温度的测量研究具有重要意义。

Temperature measurement using bandpass infrared colorimetric filter

The bandpass colorimetric filter temperature measurement theory was presented, which could accurately measure the object at medium-low temperature, meanwhile, a series of experimental facility were built up based on the theory. The facilities used were calibrated accurately and the discrete data were fitted by using numerical function, a temperature-measurement experiment was done using extended blackbody in the range of 50℃~400℃. Experiment result implies that the facility can precisely obtain the true temperature of a measured objection without the presence of target launch rate. Therefore, it proves  the validity of the theory and the feasibility of the temperature-measurement system matching the theory, which plays a key role in the accurate measurement of the medium-low temperature objects.
