摘要

提出了一种基于光学层析算法的聚焦辐射相机光学测温方法

该方法通过建立聚焦辐射相机的双锥采样模型

利用光学层析系数矩阵确定了不同位置处辐射强度与温度间的关系。分别使用十字标定板标定物距

;使用卤素标准光源标定物距

对应的最大电压;最终得到了不同距离对应的电压值拟合曲线

并进行了燃烧试验。结果表明:该方法能够有效测量燃烧火焰不同深度位置的温度分布

相机直接测量范围内相对误差不超过4.5%

外推测温相对误差不超过19.8%

具有较高的准确性。

Abstract

An optical temperature measurement method for focusing radiation camera based on optical tomography algorithm was proposed. By establishing the biconical sampling model of the focusing radiation camera

the relationship between radiation intensity and temperature at different positions was determined by using the optical tomography coefficient matrix. Firstly

use the cross calibration plate to calibrate the object distance

. Secondly

the halogen standard light source was used to calibrate the maximum voltage corresponding to the object distance

. Finally

the voltage fitting curves corresponding to different distances were obtained and the combustion test was carried out. Results show that the method can effectively measure the temperature distribution at different depths of the combustion flame. The relative error in the direct measurement range of the

camera is not more than 4.5%

and the relative error of the external estimated temperature is not more than 19.8%

which has higher accuracy.
