We can often see three–dimensional holographic communication technology in science fiction movies, using the principle of three-dimensional computer graphics, and the distant person or thing can be projected in the air in the form of a three dimensional. With the development of science, all the equipment miniaturization and precision, the display device cannot match and humans would increasingly demand a new display technology to solve the problem. The 3d holographic projection precisely fits this role.

3 d holographic projection

  1. 1. 3D HOLOGRAPHICPROJECTIONRANJAN DHAR1KT09EC0Under the guidance of :Mr. Amaresh CAssistant ProfessorDepartment of ECESKIT, Bangalore1
  2. 2. Introduction Holography is a method used to record patterns of light whichenables 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 andscattered. Second light illuminates the object to create interferencebetween both sources 3D holographic projection technology is loosely based on illusionarytechnology called as Peppers Ghost The technique of holography can also be used to opticallystore, retrieve, and process information.2

  17. 17. Importance• Popularity varies from computer graphics toother diverse environments like medicaldiagnostics , air traffic control , education, entertainment , advertising etc.• Important and Private information storedoptically in holograms – Credit cards• Additional hardware is being discarded17
  18. 18. Applications• Medical studio• Filming of Real people• Special effects• Holo-promotion• TV image projection• Cell phone deployment18
  19. 19. Future Scope• Advertising• Gaming• Education• Communication• Medical• Forensic Sciences• Memory Efficiency19
  20. 20. Conclusion• With a trend of moving towards 3D and VirtualReality, Holographic System will dominate thedisplay, advertising and entertainmentindustries• This is largely attributed to : Lowering of cost of Key Components Advancement in Holographic Technology Advancement in Technology of KeyComponents20
