TracePro在“光的偏振实验”中的应用

为提高光的偏振实验教学效果和教学质量,在教学中引入专业的光学设计软件--TracePro,利用该软件仿真了光的双折射过程和现象,以及偏振片的原理;建立光的偏振实验系统实体模型,完成光的偏振态判断实验;仿真光通过波片后的偏振态转换现象;验证马吕斯定律,并仿真了多层介质膜对光的分离和旋光现象.结果表明该方法可以提高教学效率,激发学生探索科学的主观能动性,仿真结论与理论推导和实际实验结果一致.

Application of TracePro in polarization experiment of light

In order to improve the teaching effect and teaching quality of polarization experiment of light,a professional optical design software,TracePro,is introduced into the teaching to simulate the light.The process and phenomenon of birefringence and the principle of polarizer are established,and the physical model of polarization experiment system of light is established.The parameters and conditions of each component are set up according to the requirements to complete the "whether to save or not".In the experiment of judging the polarization state of light,the polarization state conversion phenomenon of light passing through the wave plate is simulated,and Marius’ law is verified,the optical separation of dielectric film and optical rotation are simulated also.The results show that this method can improve teaching efficiency,stimulating students to explore the subjective initiative of science,and the simulation results are consistent with the theoretical and experimental results.
