[0002] Holographic projection, known as holographic cabinet in the multimedia industry, also known as "3D holographic projection", is divided into two categories: holographic cabinet and stage holography. Holographic cabinet is a stereoscopic projection effect that reflects special three-dimensional images onto the holographic cabinet through the principles of interference and diffraction. Holographic projection is a three-dimensional virtual image presented on a transparent medium through the principles of interference and diffraction. Holographic projection can not only present illusions, but also allow viewers to interact with it. Holographic projection is composed of three-dimensional model scenes, modeling lighting systems, optical imaging systems, sound systems, etc., and is suitable for exhibitions, shopping malls, museums and other occasions.
