Digital holography is a three-dimensional image, created with photographic projection. A three-dimensional picture produced via photographic projection is known as digital holography. Holograms are acquired and processed using a digital sensor array, often a CCD camera or a similar device. From digitized interferograms, image rendering—or the reconstruction of object data—is carried out mathematically.
Without requiring viewers to wear a headset, holograms enable the projection of a high-quality, three-dimensional digital depiction of an object or a person.
