Linear Polarized 3D Systems ?
Circular Polarized 3D Systems ?
which should I select ? 
 
  For most 3D theatrical environment where audiences
can be sit still during the course of show,
linear polarized system should be satisfiable.
However,for other situations where audiences' head is
constantly shaken,such as in theme-park ride,
circular polarized system is preferred.

How Does Polarized 3D system work ?

The human brain composes 3D image of surrounding from parallax, and it is possible to create artificial 3D image by having two cameras shooting the object from a slightly different perspective. By letting the right eye see the image from right camera and left eye see the image form left camera, polarized 3D system enable us to see stereoscopic images on a 2D screen.  

Linear Polarized 3D System
 
When linear polarizers are set as shown in the diagram above, it allows right eye to see only the
image comes out from right projector, and left eye to see image come out from left projector.
This create 3D (stereoscopic) image in the viewer's brain as a result.
* Light is blocked when polarizers are overlaid in a way absorption axis are orthogonal to each other.
* Light is transmitted when polarizers are overlaid in a way absorption axis are parallel to each other.










Circular Polarized 3D System
 
When Circular polarizers are set as shown in the diagram above, it allows right eye to see only the
image comes out from right projector, and left eye to see image come out from left projector.
This create 3D (stereoscopic) image in the viewer's brain as a result.
* Light is blocked when right&left polarizers are overlaid in a way lambda film sides are facing each other.

Additional Instruction with Circular Polarizer System
@ The rotating axis (of projected image) is reversed when reflected on the screen
Therefore, it is required to use left circular polarizer for right eye projector, and vice versa.
A Circular polarizer maintains light blockage even when the relative angles is altered.
However, blockage level is at its peak when absorption axis are orthogonal to each other

White screen inhibits polarization.
High refraction 3D silver screen is required for 3D projection
