偏振密码演示仪的设计与应用

DESIGN AND APPLICATION OF POLARIZATION PASSWORD DEMONSTRATOR

针对应用型本科院校大学物理教学过程中,课堂演示实验使用多以现象观察为主,缺乏学生参与仪器制作机会的问题,设计了偏振密码演示仪,并利用偏振密码演示仪设计演示场景,将其用于大学物理教学和科普活动中。通过观察演示现象、分析演示原理、设计密码拼接方案、科普展演等过程,加深学生对偏振知识的理解,提高学生应用偏振知识设计仪器、提出自己的见解及传播偏振知识的综合能力。通过与穿墙而过演示仪进行对比得出偏振密码演示仪的使用受到了更多学生的喜爱,可见偏振密码演示仪符合应用型本科院校的教学需求。

In view of the problem that in the process of college physics teaching in applicationoriented universities,classroom demonstration experiments are mostly based on phenomenon observation and lack of opportunities for students to participate in the production of instruments,a polarization password demonstrator was designed,and a demonstration scene was designed by using the polarization password demonstrator,which is used in college physics teaching and popular science activities.By observing the demonstration phenomenon,analyzing the demonstration principle,designing password splicing scheme,popular science exhibition and other processes,deepen students􀆳understanding of polarization knowledge,and improve students􀆳comprehensive ability to apply polarization knowledge to design instruments,put forward their own opinions and spread polarization knowledge.Compared with the through-the-wall demonstrator,it is concluded that the use of polarization password demonstrator is favored by more students.It can be seen that the polarization password demonstrator meets the teaching needs of Application-oriented Universities.
