PE-0800 Holography

In 1948 – before the era of lasers - Denis Gabor developed the transmission holography technique and took the first real holograms. For the invention of holography Gabor received the Nobel Prize in 1971. In 1962 Yury Nikolayevich Denisyuk developed a holography technique which allowed to observe holograms by means of white light source rather than a monochromatic  one, defined as reflection holography. Although holography did not reach the expected practical breakthrough, it is still worth to pay attention to this fascinating technique.

The experimental set-up comprises a highly coherent green laser light source and the necessary optical components to create the expanded reference and object beam. With a few further components a Michelson interferometer is formed. The imaged interference pattern is used to check if the environment is free from vibration and other disturbances. Since a green laser source is utilised, appropriate film plates and developer are provided. Besides the optical components all required tools and materials are provided to make the developer and bleaching liquids out of provided dry chemicals. For the development of the exposed film plates all paraphernalia are provided.
