结合Origin设计光的单缝衍射实验

Use origin to design light diffraction experiments

利用激光笔和动态多缝组成单缝衍射装置,装置简单、轻便,实验现象明显.利用数码摄像头拍摄衍射图样,并用Origin软件测量其光强分布及条纹宽度,测量速度快、精度高.演示过程通过投影仪展现在大屏幕上,在大课堂上演示方便易行.

Laser pointer and dynamic multi-slit diffraction device is combined into a simple,lightweight,experimental results clearly demonstrate equipment.Using digital camera shot diffraction patterns,measured by using Origin software distribution and intensity stripe width,high speed and high precision.The demonstration by showing a large projector screen for easy presentation in a large classroom.
