3D Stereo Methods

For immersive 3D displays, Visbox makes use of several 3D stereo methods including linear polarization, circular polarization, Infitec, and active stereo.

Polarized Glasses
Infitec Glasses
Active Glasses

Passive Polarized

Benefits:
– Low cost
– Lightweight

Drawbacks:
– Polarization preserving  screen required (high gain causing hotspots)
– More cross-talk (ghosting) than Infitec or Active stereo

Passive Infitec

Benefits:
– Excellent stereo separation (minimal ghosting)
– Can be used with diffuse screen materials (good brightness uniformity)

Drawbacks:
– Expensive
– Color correction required
– Limited field of view

Active Stereo

Benefits:
– Excellent stereo separation (minimal ghosting)
– Can be used with diffuse screen materials (good brightness uniformity)
– Wide field of view

Drawbacks:
– Expensive
– Glasses require charging
