Diffuse reflection

Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection.An ideal diffuse reflecting surface is said to exhibit Lambertian reflection, meaning that there is equal luminance when viewed from all directions lying in the half-space ...

Holography – University Physics Volume 3

A hologram, such as the one in (Figure), is a true three-dimensional image recorded on film by lasers. Holograms are used for amusement; decoration on novelty items and magazine covers; security on credit cards and driver''s licenses (a laser and other equipment are needed to reproduce them); and for serious three-dimensional information storage.

3-D reflection/hologram of 4-D object

 · (loosely inspired by the discussion of mirrors in this thread If I''m looking at a mirror, or a image on holographic film, I can tell that the image I''m looking at is in some sense 3-d, even though it appears on a 2-d surface. For instance, I can observe parallax – if I move side to side, objects in the mirror or hologram appear to move relative to each other. This doesn''t happen …
