When an airy disk is formed, does using a polarizer in front of the pinhole change the shape of the disk?
No responses? Well I'm going to guess yes, and hourglass shaped. I might be able to test this for you with my telescope and a lunar filter...zincshow said:When an airy disk is formed, does using a polarizer in front of the pinhole change the shape of the disk?

A polarizer is a device that filters light waves based on their polarization direction. When light passes through a polarizer, it only allows waves with a specific polarization direction to pass through, while blocking all others. This can affect Airy disks by changing the intensity and shape of the diffraction pattern produced by the light passing through a circular aperture.
To conduct an experiment, you will need a light source, a polarizer, and a circular aperture. Place the polarizer between the light source and the aperture, and rotate it to different angles while observing the diffraction pattern produced on a screen placed behind the aperture. Take measurements of the intensity and shape of the diffraction pattern at different angles of the polarizer to analyze the effects.
Several factors can influence the results, such as the wavelength of the light source, the size and shape of the aperture, and the material and orientation of the polarizer. The distance between the aperture and the screen, as well as any external light sources, can also affect the results.
Understanding the effects of a polarizer on Airy disks can be useful in various fields such as optics, astronomy, and microscopy. It can help in the design and optimization of optical systems, as well as in the analysis of astronomical images and microscopic samples.
Yes, the principles and concepts learned from exploring the effects of a polarizer on Airy disks can be applied to other diffraction patterns. However, the specific results may vary depending on the characteristics of the aperture and the light source used in the experiment.
