3D HOLOGRAPHIC PROJECTION

  1. 1. 3D HOLOGRAPHIC PROJECTION Under the Guidance Of: Presented By: Mrs. BASIMA YOOSAF AJITH KRISHNAN Assistant Professor Roll No : R11U001 Department Of CSE Class : S7, CSE
  2. 2. CONTENTS • INTRODUCTION TO HOLOGRAPHY • HISTORY OF HOLOGRAPHY • WORKING OF HOLOGRAPHY • IMPORTANCE AND NEED OF 3D HOLOGRAPHIC PROJECTION • WORKING OF 3D HOLOGRAPHIC PROJECTION • ADVANTAGES OF 3D HOLOGRAPHIC PROJECTION • APPLICATIONS OF 3D HOLOGRAPHIC PROJECTION • CONCLUSION • REFERENCES
  3. 3. INTRODUCTION TO HOLOGRAPHY • Holography is composed of the Greek terms, "holos" for "whole view" and “gram” for "writing or drawing“ • Technical term for holography is wave front reconstruction • Image changes as the position and orientation of the viewing system changes • Records phase of the object • Record our three dimensional world on a two dimensional recording medium
  4. 4. INTRODUCTION TO HOLOGRAPHY (cont) • Can be seen using naked eyes • Demonstrates complete parallax and depth-of-field • Image floats in free space • Can also be used to optically store, retrieve, and process information
  5. 5. HISTORY OF HOLOGRAPHY • Dennis Gabor - discovered the basic technology of holography in 1947 • Optical holography did not really advance until the development of the laser in 1960 • First practical optical holograms that recorded 3D objects to be made in 1962 • Yuri Denisyuk from Soviet Union • Emmett Leith and Juris Upatnicks from USA • Advanced notably since the 1980s owing to low-cost solid-state lasers Dennis Gabor (1900-1979)
  6. 6. TIMELINE OF HOLOGRAPHY
  7. 7. WORKING OF HOLOGRAPHY • Requires a laser as the light source • Image is captured as interference pattern • Working of holography is divided into two phases: • Recording • Reconstruction •Produce monochromatic light
  8. 8. COMPONENTS REQUIRED • Laser • Usually helium-neon (HeNe) lasers are used • Beam splitter • Device that uses mirrors and prisms to split laser beam into two beams • Object beam • Reference beam • Mirrors • Direct the beams of light to the correct locations • Holographic film • Can record light at a very high resolution • Layer of light-sensitive compounds on a transparent surface ( Silver Halide Photographic Emulsion )
  9. 9. RECORDING A HOLOGRAM Optical arrangement of recording a hologram
  10. 10. RECORDING A HOLOGRAM(cont)
  11. 11. RECORDING A HOLOGRAM(cont) Two dimensional interference pattern caused by reference beam and object beam
  12. 12. RECONSTRUCTING A HOLOGRAM Optical arrangement of reconstructing a hologram
  13. 13. A SUCCESSFUL HOLOGRAM USING HELIUM NEON LASER
  14. 14. IMPORTANCE AND NEED OF 3D HOLOGRAPHIC PROJECTION • Rapidly growing technology • Project large-scale, high-resolution images onto free space • Accommodate multiple viewers independently and simultaneously • Create tremendous effects on all fields of life including business, education, science, art and healthcare • Enabling viewing and manipulation of virtual 3D objects in 3D space without the need for special viewing goggles or headgear
  15. 15. EVOLUTION OF DISPLAYS
  16. 16. PROJECTED COST OF 3D HOLOGRAPHIC PROJECTION
  17. 17. WORKING OF 3D HOLOGRAPHIC PROJECTION • Also known as ''Musion Eyeliner'‘ • Loosely based on an illusionary technique called Peppers Ghost • John Henry Pepper - attempted to popularize the effect A setup for Pepper's Ghost
  18. 18. WORKING OF 3D HOLOGRAPHIC PROJECTION(cont) • Latest and vary unique Hi Definition 3D Projection Technology • Image is captured in 3 dimensional Aspect with a Special Hi Definition Camera on a specially built stage • Projected at various Distant Locations • Without wearing any kind of 3D glasses
  19. 19. WORKING OF 3D HOLOGRAPHIC PROJECTION(cont) • It starts with the patented foil, completely invisible to the naked eye, right at 45° across the stage • Holographic display is based on a Spatial Light Modulator A setup for Musion Eyeliner
  20. 20. WORKING OF 3D HOLOGRAPHIC PROJECTION(cont)
  21. 21. DISPLAY SETUP • A video projector, preferably DLP with an HD card/minimum native resolution of 1280 x 1024 and brightness of 5000+ lumens • A hard-disc player with 1920 x 1080i HD graphics card, Apple or PC video server, DVD player • A Musion® Eyeliner™ Foil(1/8" thick Acrylic version) and a stage set • Lighting and audio as required • Subjects are filmed in HDTV and broadcast on to the foil through HDTV projection systems, driven by HD Mpeg2 digital hard disc players, or uncompressed full HDTV video
  22. 22. WHAT WE COMPUTER ENGINEERS CAN DO IN THIS HOLOGRAPHY? • Can describe all of the interactions between the object and reference beams, as well as the shapes of the interference fringes, using mathematical equations • Makes it possible to program a computer to print a pattern onto a holographic plate, creating a hologram of an object that doesn’t actually exist
  23. 23. COMPUTER AND HOLOGRAPHY
  24. 24. COMPUTER AND HOLOGRAPHY(cont)
  25. 25. ADVANTAGES OF 3D HOLOGRAPHIC PROJECTION • A high resolution three dimensional images • Glasses free 3D display • No need for projection screen • Life like images • Interactive display
