Project Description

Fabrication of holograms is generally complicated and expensive. Therefore, it was studied, how to create high-quality computer-generated holograms using only affordable and widespread equipment. To make binary amplitude holograms with customized diffraction patterns, a computer program was written and photographic reduction with a film camera was used. The optimal parameters of the fabricated holograms as well as differences between using three different film types were determined. It was found that all film types are suitable for fabrication and in addition to laser light, the diffraction patterns are clearly visible when a mobile phone flashlight is viewed through the holograms. Such holograms can be used, for example, in physics lessons, science events, or escape rooms.
