Passive Stereo Screen
Excellent Stereo Separation
When excellent passive stereo separation is achieved by
integrating Barco projectors with polarization
technology, it is perfectly maintained by the
optimal
non-depolarizing properties
of Barco’s proprietary
PASCAD passive stereo screen.
Requirements
While screens should be as
rigid
as possible in order to
prevent distortion of the projected image, they must
also have the
flexibility
to pass through doors or
windows to reach an installation site. When used on
the floor of an immersive cubic environment, the
screen must be
solid
and stable enough to support
several people, yet
thin
enough to prevent doubled
images. There should be no visible seams between the
walls, floor and ceiling.
Barco can deliver single sheets of screen material with
widths up to 7.5m (24.6 feet), heights up to 3.5m
(11.5 ft), and thicknesses from 0.8mm (0.032 inch) to
75mm (3 inch).

ACTCAD
Active Stereo Screen
After extensive testing of numerous different screen
materials, which were selected based on a thorough
understanding of their mechanical and optical
characteristics, Barco has developed its proprietary
ACTCAD screens. Delivering a
higher brightness
level
and
better color uniformity
than standard diffuse
screens, the ACTCAD screen offers
optimal viewing
from almost any angle
