Introduction
Holography under room light is referred to as hologram recording and developing under room light using a photopolymer plate. By contrast, a conventional silver salt plate must be operated (exposing, developing, and fixing) in a darkroom. The advantage of room-light holography with white-light reconstruction is the convenience of operation with a high diffraction efficiency, so that the image of the object can be reconstructed very well. The instruction manual contains comprehensive materials including experimental configurations, principles, step-by-step instructions, and required parts. Please click to view some sample pages of the instruction manual.
This kit can be used to conduct the following experiments:
1. Fresnel (transmissive) holography
2. Reflective holography
3. Image plane holography
4. Two-step rainbow holography
5. One-step rainbow holography
