电子计算机辅助红外断层摄影技术,是一项把红外测试技术应用于加热设备内壁热场分布检测的高新技术。加热设备内部热场的变化,由于热传导必然反映到设备外部,用热像仪可测出表面温度分布热图,已知表面温度值求解系统的几何形状,是热传导问题的一种反运算。本文详细地介绍了应用电子计算机求解这类反问题的一种通用解法,最后简述了提高计算精度的途径。 Computer-aided infrared tomography is a high-tech technology that applies infrared testing technology to the thermal field distribution of heating equipment. Because the heat conduction must be reflected outside the equipment, the heat map can be used to measure the surface temperature distribution heat map. Knowing the surface temperature value to solve the geometry of the system is an inverse operation of the heat conduction problem. In this paper, a general solution to solve this kind of inverse problem by using electronic computer is introduced in detail. At last, the ways to improve the calculation precision are described briefly.
