Circular Aperture Diffraction and Interference

Laser Module and Circular Aperture

Concept Overview:

1. Visualization of Airy's Disk and Concentric Circles

2. Visualization of interference of circular patterns produced by 2 holes

Lecturer Procedure

Step(s) to Follow Expected Result

1. Insert single hole disk.

2. Turn on laser.

3. Use dials to adjust as needed to produce image
