the resulting diffraction pattern is similar to the diffraction pattern of a small circular aperture (Airy's disk pattern). The difference is that in a lycopodium powder diffraction, light gets ...

Turn off the laser. Turn on the laser. Turn off the room light to see the diffraction pattern more easily. Point out the Airy's disk diffraction pattern. Use a blank sheet of white paper as a screen ...

This diffraction causes the light to form a diffraction pattern, known as the Airy disk, at the focal plane of the microscope. The Airy disk consists of a central bright spot surrounded by concentric ...

An Airy beam is a very unusual ... Other advantages include its immunity to normal spreading (diffraction) and self-healing capability, which renders the light beam capable of 'repairing' itself ...

As shown earlier, the image will then be a perfect Airy disk. This is, in effect, the reverse of our earlier example where we threw a rock into a pool of water to illustrate the wave nature of light ...
