Holography is a technique that enables a wavefront of light to be recorded and later reconstructed when the original wavefront is no longer present. Holograms preserve the same visual depth cues as a real object and present highly realistic and immersive visual experiences, making them particularly suited for the presentation of technical concepts, showcasing products or creating a ‘wow’ factor at branding events. Holography can be considered similar to sound recording where a sound field is reconstructed at a later date without the original source, but it is perhaps most similar to Ambisonic sound recording (See SA’s report on Innovative Audio), in which any listening angle of a sound field can be reproduced in the reconstruction.
Holograms are distinctly different to 3D or virtual reality displayed on a 2D computer screen because a hologram is a truly 3D and free-standing image that does not simulate spatial depth or require a specialized headset or accessories to view. This is an important distinction as it allows unlimited visualization of 3D images / interaction in immersive environments without the nausea, eye-fatigue or visual discomfort, commonly associated with other ‘3D’ technologies such as VR headsets.
The aim of this report is to provide vendor profiles of the main companies that are active in the area of holography and particularly its applications. This list is not exhaustive; the accompanying excel spreadsheet “Holography Vendor Database” further details vendors of this technology that also contribute to this industry.
