computer-generated holography

Computer-generated holography (CGH) is a technique that uses computers to create holograms, which are three-dimensional images formed by the interference of light waves. Unlike traditional holography, which captures real light waves from an object, CGH calculates how these waves would interact and maps this information digitally. This allows for the production of complex visual representations, useful in various fields such as art, science, and technology. CGH can be applied in optical devices, data storage, and even in medical imaging, enabling advancements in how we visualize and interact with three-dimensional data.
