Unformatted text preview: Demo Lab 2 Katie Bredice Wednesday Section Henry Wen Holography 31 October 2007 Holography is a way to capture images with three discernable dimensions. The purpose of this lab was to demonstrate one method of holography and study how all of the information is captured on the film. The specific type of hologram created in this lab was a white light hologram, meaning that the hologram is visible when white light is shone on it. The production of the hologram required two coherent beams of light. These two beams were generated from a single laser beam and a beam-splitting device. One beam, called the reference beam, shines directly on the photographic film. Mirrors direct the other beam to the object whose image is to be recorded. Light scattered from the object to the photographic film is called the object beam. Since these beams are coherent, they interfere and the photographic film records that interference pattern. The film was exposed for eight seconds so that it would have enough time to register the pattern....
