用CCD成像方法辅助课堂演示实验

Using CCD imaging method to assist demonstration experiment in class

介绍了一种CCD成像方法,该方法可以实时地对较小的演示现象成像,并在大屏幕上即时展示出来.该方法可以把较大的演示教具做得较小,更便于制作、携带和存放,同时可以将原来不适合做课堂演示的实验内容扩展到课堂演示内容中,可以增加演示内容.本文以陀螺演示实验、激光光源测量普朗克常量实验及放大演示结构性演示教具实验为例,详细介绍了CCD成像法的应用.

A CCD imaging method was introduced,which could image small demonstrating phenomena in real time and display them on a large screen.The method could make the larger teaching aids smaller,which is more convenient to make,carry and store.Using this method,some experimental contents that had not been suitable for the classroom demonstration could be introduced into the classroom.In this paper,the applications of CCD imaging method were introduced in detail,taking the gyro demonstration experiment,the Planck constant measurement experiment with laser source and the structural demonstration experiment with amplification demonstration as examples.
