Stereoscopic vision( 立體視覺 )

Principles:Two eyes see different images ( 6~8cm)Angle of parallax( 視差 ) (to judge distance)

→“Stereoscopic vision” appears!

Most Important Concept The technologies to be introduced all have the

same purpose:

6

To make your left eye and right eye see different images in order to create the 3D effect!

Anaglyph (red-blue) glasses

1.Anaglyph images 2.two color glasses (Anaglyph glasses) 3.Images are made of two color layers

cyan ( 青色 )

red

chromatically opposite

10

Polarization glasses( 偏光眼鏡 )

How does it work?1. two projectors

2. use polarized light ( 偏光 ) principle

3. see separate image in our eyes.

4. Combine two image to cause 3D secne

Technique -using naked eye

Parallax barrier( 視差屏障式 )

How does it work?1. Use liquid crystal display (LCD)

2. consist of a layer of precision slits (to filter the light)

different images

13

Lenticular Lens( 柱狀透鏡式 )

How does it work?1. an array of magnifying lenses( 凸透鏡 ) on the

screen

2. refract light to show different images to the eyes

13

Lenticular Lens

different images

14

Directional Backlight( 指向光源式 ) How does it work?

14

1. use two set of LED that show two images

alternately in high speed

2. The left part of the backlight is related to the right eye, and vice versa( 反之亦然 ).

In the past impossibleunimaginable

NowadaysRapid developmentadvanced ＆ stunning

contrast

Our dream is “visualized”!!!

WHY?
