Introduction


The LEOK-64 Hologram Recording Under Room Light kit is designed to enable students to record and develop holograms under normal room light, a significant advancement over traditional methods that require darkroom conditions. This is achieved using a photopolymer plate, which allows for white-light reconstruction of holograms with high diffraction efficiency. The advantage of this technique is the ability to perform holographic experiments in a convenient environment, while still achieving clear and high-quality holographic reconstructions.


This kit is particularly useful for educational purposes, as it simplifies the process of recording and developing holograms, making it easier for students to explore and understand holography without the need for a darkroom. With its white-light reconstruction, students can observe the 3D images clearly and easily, facilitating a deeper understanding of the principles behind holography.


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
