Viewing angle

the angle at the surface of a hologram which defines the limits of the space relative to the hologram in which an image can be observed with acceptable visual performance.

a technology that immerses the viewer into a computer-generated simulation of a three-dimensional scene and allows them to interact with it using a digital interface. VR devices often use the term ‘hologram’ to describe the heightened sense of realism they...

Volume hologram

otherwise known as a Bragg diffraction hologram, is where the thickness of the recording material is much larger than the wavelength of the light used for recording. The advantage of volume over surface relief holograms is the gain in image quality.
