3What is holography

Holography is a technique that allows the light scattered from an object to be recorded and later reconstructed.

The technique to optically store, retrieve, and process information.

Preserve the 3-D information of a holographed subject

4Why holographic display

A high resolution three dimensional recording of an object

Glasses free 3D display No need for projection screen Life like images Interactive display

6How holograms work The time-varying light field

of a scene with all its physical properties is to be recorded and then regenerated. Hence the working of holography is divided into two phases:•Recording•Reconstruction

8Recording a hologram

9Process

When the two laser beams reach the recording medium, their light waves intersect and interfere with each other. It is this interference pattern that is imprinted on the recording medium.
