Holography
Making 3D pictures, conceived by: Gabor Denes (1947)
3D pictures: possible to view it from different perspectives (looking around the object)
holo--> complete; gram--> message
holography --> preserving all information about an object
holograms: made by using laser light
on the film interference pattern of
1. Laser light coming directly from the light-source
2. Laser light reflected by the object
(3D information about the object on each portion of the film)
