PPT-Holograms

Roger Rothenberg Record of light scattered from an object Same light field is reconstructed without original object present Requires laser for tight control of light source and light field Appears 3dimensional. These discoveries were made by Emmett Leith and Juris Upatnieks working at the Radar and Optics Lab of the University of Michigans Willow Run Laboratories They were working on optical data processing for a highly secret new form of sidelooking radar phic information is transferred from light sensitive glass plates to nickel embossing shims. The holographic images are "printed" by stamping the interference pattern onto plastic and then backing the CPC - G03H - 2015.04 1 ; producing stereoscopic or other three-dimensional effects G02B 27/22 ; diffraction-grating systemsG02B 27/44 ; systems using moir Muhammad Hasan Danish Khan.

Is a technique that allows the light scattered from an object to be recorded and later reconstructed so that when an imaging system (a camera or an eye) is placed in the reconstructed beam, an image of the object will be seen even when the object is no longer present. . a multidimensional . issue.

Hologram is come from word ‘HOLOS’ is ‘whole view’ and ‘Gram’ come from ‘written’, both words are from Greek. Holograms is a way to views image that is 3D and have depth. Holograms can de defined as the true 3D image, because we can view all around of the object, not only the object but the object behind it. Hologram require laser because they need a light with exact wave length. the Holograms record the positive . Star wars. Team Project: Technology in Movies. Team 8. Introduction of the technology.

Can you create a simple reflective hologram using your smartphone, and if so how?. Holograms require flat translucent surfaces to reflect light off of. The light bounces off the walls to create a replicated image. The image can be still (picture) or with motion(video). Holograms in large scale can appear to be real, but they have no physical mass and have a transparency to them. Only one sensory applies to holograms; Sight. For my experiment I have chosen one of the simplest ways to demonstrate what I’ve mentioned above.. Lecture 3 Three exercises in hologram analysis. David J. Brady. Duke University. Lecture 3.
