NEW holography TECHNOLOGY ALL PPT

  1. 1. WHAT IS HOLOGRAPHY?  Holography (from the Greek, whole + write) is the science of producing holograms  It is an advanced form of photography that allows an image to be recorded in three dimensions.  The technique of holography can also be used to optically store, retrieve, and process information.
  2. 2. HOLOGRAPHIC PROPERTIES  If you look at these holograms from different angles, you see objects from different perspectives, just like you would if you were looking at a real object  They usually just look like sparkly pictures or smears of color  If you cut one in half, each half contains whole views of the entire holographic image
  3. 3. HISTORY Dennis Gabor - Father of Holography and Holographic Technologies Dennis wrote a paper in 1948 that has become the foundation of modern Holography. The most interesting thing about all this is that laser light had not even been invented yet, when he wrote his paper
  4. 4. PRINCIPLE Holography is a two-step process. The second step is the reconstruction in which the hologram is transformed into the image. First step is the recording of hologram where the object is transformed into a photographic record.
  5. 5.  A Hologram is the result of interference occurring between two waves,  an object beam which is the light scattered off the object & a coherent background,  the reference beam, which is the light scattered off the object & a coherent background, the reference beam ,  which is the light reaching the photographic plate
  6. 6. Photography vs. Holography Conventional photography Film sensitive only to intensity distribution. 2-d dimension of a 3-d scene (object). Photograph lacks depth perception.
  7. 7. Hologram:  Converts phase information into amplitude information (inphase - maximum amplitude, out-of-phase – minimum amplitude).  Interfere wavefront of light from object beam with a reference wave.  The hologram is a complex interference pattern . It’s a kind of diffraction grating. If you tear a hologram in half, you can still see the whole image in each piece.The same is true with smaller and smaller pieces.
  8. 8. ENTERTAINMENT TEACHING AND TRAINING VIRTUAL COMMUNICATION SIMULATION AND PLANNING MILITARY AND SPACE APPLICATION
  9. 9. TEACHING AND TRAINING ONE ON ONE WITH VR HOLOGRAPHIC IMAGES GUEST SPEAKER BUREAU IS YOUR PROFESSOR REAL? SPORT TECHNIQUE COACHING AND TRAINING
  10. 10. VIRTUAL COMMUNICATION RECORD YOURSELF FOR FUTURE GREAT GRANDCHILDREN VIRTUAL SALES PRESENTATION CORPORATE MEETINGS WITHOUT TRAVEL STATE DEPARTMENT VR THE PRESIDENTIAL VISIT
  11. 11. PLANNING AND SIMULATION  DISASTER PLANNING  TRAFFIC,TRANSPORTATION  DISTRIBUTION FLOWS
  12. 12. MILITARY AND SPACE APPLICATION HOLOGRAPHIC DECOYS AND DECEPTION APPLICATIONS VR TRAINING AND MIND CONDITIONING HOLOGRAPHIC CHECK POINTS HOLOGRAPHIC TECH IN SPACE
  13. 13. CONCLUSIO N HOLOGRAPHIC TECHNOLOGY HAS ENDLESS APPLICATIONS AS FAR AS THE HUMAN MIND CAN IMAGINE HOLOGRAPHIC TECHNOLOGIES ARE NOT JUST ABOUT ART OR BUSINESS COMMUNICATION, THEY ARE ABOUT SAFETY , SECURITY , EDUCATION , PLANNING AND THE STRENGTH OF OUR CIVILIZATION HERE AND BEYOND  HOLOGRAPHIC TECHNOLOGY WILL BECAME A VERY INTEGRAL PART OF HUMAN SOCIETIES AND CIVILIZATIONS IN THE FUTURE
