摘　　要：光度学是研究由电磁辐射能所引起的人眼刺激大小的一门科学。在光电检测以及照明光学中,了解光源辐射光的光度学量在传输过程所遵循的规律是极其必要的。作为相关课程中的重难点,这部分内容的教学一直备受教师和学生的关注。Trace Pro软件基界面友好,易于实现光学系统的照度、光强分析,非常适合在教学中演示光度学的基本定律。首先列出光度学中三个基本定律的推导过程,然后详细探讨在Trace Pro软件中如何对这三个基本定律进行教学演示,以期让学生对较为复杂、抽象的光度学概念和定律产生直观的认识,理解得更加深刻。Photometry is a science which studies the stimulation ofhuman eyes caused by electromagnetic radiation. In courses such asphotoelectric detection and illumination, it is extremely necessary tounderstand the photometry law of radiation followed in the transmission process. As the most important and dif？ cult part of relatedcourses, the teaching of this part has been paid much attention byteachers and students. TracePro software is very suitable for the teaching demonstration of basic law because of friendly interface andconvenience in analyzing illumination and light intensity of opticalsystem. In order to let the students have intuitive understanding ofthe complex and abstract concepts and understand the law of photometry more profoundly, this paper gives a derivation of three fundamental laws in photometry ？ rstly, and then discusses in detail howto carry out teaching demonstration of the three basic laws in TracePro software.
