为了提高非接触式光纤温度传感器的精度与适用性,必须从根本上改变现有的差分法或单值模拟的方法,设法消去待测体发射率的影响。本文提出,采用光纤比色测温传感技术,可以消除待测体的发射率。
In order to improve the accuracy and applicability of the non-contact optical fiber temperature sensor, existing methods of differential or singular value simulation must be fundamentally changed to eliminate the influence of the emissivity of the sample to be measured. This paper proposes that the fiber optic colorimetric temperature sensing technology can eliminate the emissivity of the body to be measured.
