Open in App
Solution
The correct option is B holography
Holography is used to display a fully three dimensional image of the holographed subject, which is seen without the aid of special glasses or intermediate objects. The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of seemingly random variations in the opacity, density, or surface profile of the photographic medium. When suitably lit, the interference pattern diffracts the light into a reproduction of the original light field and the objects that were in it appear to still be there, exhibiting visualvisual depths cues such as parallax and perspective that change realistically with any change in the relative position of the observer.
