optical holography

Optical holography is a technique that records and displays three-dimensional images using the interference of laser light. When a laser beam is split, one part illuminates the object and the other acts as a reference. The light waves interact and create an interference pattern captured on a recording medium. When illuminated with a laser again, this pattern reconstructs the original light waves, producing a lifelike 3D image that can be viewed from different angles. This process preserves depth, perspective, and other visual details, making holography a powerful method for realistic 3D imaging in science, art, and data storage.
