  1. What you want to know…

  2. 3-D Television A Scientific Perspective

  3. History of 3D Imaging • 3D imaging in not new • Been around for more than 150 years • 1st patented Sir Charles Wheatstone 1838 • Stereography

  4. 3DTV Begins • “3DTV: It’s an Eye-Opener” • The first domestic 3D Television broadcast • Wednesday night 3/24/2010 • Rangers vs. Islanders NHL game • Described as “game-changing experience” Photos: multichannel.com

  5. How 3D Works • Binocular Vision • ancient Greece – Euclid • Eyes are 2 inches apart • Each ‘sees’ slightly different picture • Brain puts it together to provide depth

  6. How 3D Works • We can simulate this by viewing two pictures taken from slightly different angles while cross-eyed

  7. RED / BLUE (anaglyph) 3D • When light passes through a red or blue filter, it filters out that particular wavelength of light • Taking advantage of this and combining it with binocular vision we get basic 3D glasses

  8. Polarized 3D • Polarizing the two different images projected on the screen allows us to do this in a different way • Does not distort color

  9. New TV’s • Different Type of Technology…

  10. The Active “blocking” method

  11. Lenticular Displays
