The Evolution and Science of 3D Television: A Historical and Technological Perspective

Discover the fascinating history and science behind 3D television, a technology that has captivated viewers for over 150 years. Beginning with Sir Charles Wheatstone's patent in 1838 and evolving through multiple innovations, the first domestic 3D broadcast took place during an NHL game on March 24, 2010. Learn how 3D imaging works through concepts like binocular vision, stereography, and sophisticated technologies including polarized and active blocking methods. Explore the journey of 3D imaging from its historical roots to its present-day applications.

  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
