W29: Fourier Optics Kit |
| Abstract: |
In an imaging system, such as a microscope, image formation can be understood as the interference of light diffracted by the sample and collected by the objective lens. The Fourier transform of the object is found in the back focal plane of the lens, otherwise known as the Fourier plane. The image of the object, which is formed by a second lens, can be altered in a variety of ways by manipulating the pattern in the Fourier plane. In this kit, an etched, chrome-on-glass target with fourteen different patterns serves as the object. In the workshop, we alter the patterns in the Fourier plane to help a Smiley escape from prison, alter the direction of a diffraction grating, open the door of a house and more. Fourier optics allows students to enhance their understanding of Fourier transforms in general and image formation in particular. |
