Pair of passive stereo glasses
Images at double
refresh rate on a
non-depolarizing screen
Two 3D optimized
LCD projectors
Linear-polarized
Barco glasses
are matched to linear-
polarized Barco projectors, and they offer an excellent
quality-to-price value for
stereo viewing with large
audiences
.
Circular Polarization
With circular polarization, the viewer can tilt his head
and change his viewing angle relative to the
stereoscopic projection display, because the light is not
polarized in a single direction.
As this high-end technology demands
greater
precision
and requires a tighter match between the
polarizing filters in the light path of the projectors and
those in the glasses, the use of
Barco high-quality
circular eyewear
is recommended.
Easy to use and comfortable to wear
, polarized
passive stereo eyewear have no active components and
are thus
very affordable for large audiences
.
Overview Barco glasses: www.vr.barco.com
Some alternative technologies available today, like
Barco I
NFITEC
, incorporate stereo information into the
color wavelengths of the projected image.
This solution results in excellent separation, especially in
combination with DLP™ projectors, while reducing the
color range and brightness.

Barco LCD projectors are each internally
polarized
to its corresponding left and right eye
information, eliminating the requirement for external
filters. With Barco’s internal polarization 70% of the
original light output is maintained, making this
technology
the most efficient method available
to
obtain
high stereo lumen brightness levels
