红外线成像实验教学研究与实践

摘要

In accordance with the teaching practice of medical physics experiment, this paper studies the significance of the experiment of infrared imaging and image analysis, it describes the necessity of carrying the experiment of infrared imaging on the course of medical physics experiment. According to the process of infrared instrument imaging, from the point of view to learn the character of infrared radiation and the physical principle of thermal imaging, this paper designs the following experiment contents:specifying the temperature measuring range, measuring the temperature of the body surface, the influence of distance and angle on temperature measuring, studying the radiation rate of different materials, thermal image analysis, etc. The paper also makes a discussion on the teaching reforming to improve the students' ability on practice. This paper makes the experiment play a proper role to make the students master the character of infrared radiation, the physical principle of thermal imaging,and improve the students' ability on practice.%本文结合医学影像物理学实验的教学实践,研究了红外线成像原理及图像分析实验教学的意义,阐述了在医学影像物理学实验教学中开设红外线成像实验的必要性；根据红外热像仪的成像过程,从学习掌握红外线辐射特性及红外线热成像的物理原理角度,设计了确定测温范围及体表温度的测量、距离与角度对测温的影响、不同材料发(辐)射率的研究、热图像分析等具体实验内容,并对在实验中提高学生实践能力等方面的教学改革做了探讨,使红外线热成像实验在学生掌握红外线辐射特性、红外线热成像的物理原理及提高学生实践能力方面较好地发挥出其应有的作用.
