The document provides a history of 3D technology, beginning with William Friese Greene's 1880 patent and continuing through developments like Frederic Eugene Ives' 1900 3D camera and the 1922 premiere of the first 3D film. It discusses various 3D display methods including anaglyph, polarization, eclipse, interference filter technology, Pulfrich, spectral separation, and lenticular/barrier screens. It also covers technologies like LCD shutter glasses, polarized glasses, and autostereoscopic displays that do not require glasses.

2.  1980: William Friese Greene obtained first
patent
 1900: 3D camera by Frederic Eugene Ives
 1915: Tests in Astor Theater, New York city
by Edwin S Porter and William E via Red-
Green anaglyph
 1922: Earliest confirmed 3D movie “The
power of love” in Ambassador hotel theater
Los Angeles.

3.  1922: Teleview system- alternate left right
images projected synchronized with arm
rests of seats.
 1922: First Red-Blue anaglyph movie
 1936: MGM presented Academy Award and
Best short Subject award winning movie
”Audioskopiks”

4.  Anaglyph
 Polarization
 Eclipse Method
 Interference filter technology
 Pulfrich
 Spectral separation
 Lenticular or barrier screen

5.  Earliest method
 Introduced in 1915
 Superimposing two images, one left eye
oriented (RED) another right eye (CYAN)
 Can be used in TV broadcasting easily
 Actual color is not recreated successfully

6.  In this system, two images are displayed on the screen, one
in red and the other in blue (or green).
 The filters on the glasses allow only one image to enter
each eye, and our brain does the restrest

8.  The active shutter glasses required for the 3D
technology is categorized into two main kinds
which are called as…
liquid crystal shutter glasses
display glasses.

10.  Polarized at 45 degree and 135 degree (90
degree difference)
 RealD glasses
 Circular polarization preferred over linear,
since viewer need not to align himself/herself
according to the image orientation
 4K projector projects 2K images on screen

11.  Metallic screen makes it effective (silver
screen), polarization not destroyed,
introduced by Thomson Technicolor.
 It reduces overall image brightness and
contrast.

12. Projection of Images working of polarizing glasses

13.  LCD Shutter glasses are used
 Do not require silver screen
 Brightness and contrast maintained
 LCD valves the work by rotating the light
between two opposite polarizing filter
 Expensive glasses

14.  Different wavelength of RED CYAN BLUE for
each eye (Dolby 3D)
 Appropriate filters for each eye
 PANAVISION introduced 5 filter per eye ove r
Dolby 3D
 Claims to be cheaper than Dolby 3D and can
be viewed on almost all projectors and
screens unlike Dolby 3D

15.  Based on human eye sensitivity for different
light intensity
 Body moves from left to right at some pace
and left eye covered with darker lens
 It creates a two images illusion
 Not widely used

16.  Uses holographic film in glasses that create
dispersive prism like effect
 Causes “redder” objects perceived as near
then “bluer” objects

17.  Superimpose two images
 Same sheet
 Alternating strips
 Screen having narrow lenses allows one
image to be shown at some particular angles
(using parallax)

19.  Lenses when made cylindrical reflects light at
acute angle
 Viewer have to sit at an angle about 90
degree
 Restricts number of viewers
 Not widely in use

20.  Without glasses
 Autosterioscopic LCD screens
 Introduced by “Sharp” in 2004
 Autosterioscopic mobile screens by Japan in
2009 (Hitachi)
 Gaming devices: Nintendo 3DS

21.  A motion film standard
 70mm film projection
 8 stories high screen (silver light)
 One of the best 3D experience

22. STRENGTHS
•Unique experience (realistic feel)
•Companies producing 3D flat displays
are well-known in the industry such as
Sony and Toshiba
•Partnerships – with movie industry
•Wide coverage of technology
•Wide array of R&D teams
WEAKNESSES
•Costly
•Slow development of underlying
technology
OPPORTUNITIES
•Technology on the rise
•Technology trigger (booming)
•Improving economy
•Industry competition
•Publicity
THREATS
•Leakage of critical information
•Piracy of employees
•Fast-phased technological environment –
can be easily phased out

23.  Cheoptics360
 Realistic holograms
 Using pyramidal fog screen and multi
projection techniques
