Introduction

Holography is a method used to record patterns of light which enables 3D images to be made called as Hologram

Hologram is a Greek term Holo – whole view & Gram – written

Light source is projected onto the surface of an object and scattered. Second light illuminates the object to create interference between both sources

3D holographic projection technology is loosely based on illusionary technology called as Peppers Ghost

The technique of holography can also be used to optically store, retrieve, and process information.
