摘要
设计自制了投影式多波长反射、透射牛顿环干涉演示仪。该演示仪将装有毛玻璃屏的遥控变色发光二极管(LED)分别安装在牛顿环仪的前后两侧,通过开关控制两个光源独立或同时发光。用遥控器可以控制光源颜色和闪烁模式。牛顿环反射或透射干涉的图案通过带有VGA信号功能的CCD摄像机拍摄并在显示器或投影仪上显示出来,供全体师生观看研究,实现了薄膜干涉的课堂演示。该演示仪体积小巧,便于携带,操作简便,适合教学应用。
The projective Newton's ring inference demo-set is designed and manufactured. This set installs Two remote-controlled Variable color light-emitting diode(LED) are installed in the front and back sides of Newton's ring equipment. The LED is covered with frosted glass. The two light resources independently or simultaneously emit lights by controlling the switch. The light resource's color and flashing mode can be controlled by the remote controller. The pattern of Newton's ring inference is shoot by the CCD camera which equipped with VGA port and then, display on the monitor or projector, offer to all of the teachers and students to watch and research. This set achieves the class demonstration of film interference. This set is small-sized, easily to carry and manipulate, suitable for teaching.
