Lumens
With stereo projection,
light output is at least
halved
in the process of creating a separate left and
right eye picture. Projectors employing different
technologies but with the same ANSI lumen specs can
give quite different stereo lumen results. The
stereo
lumen
is the
only practical value
for accurately
measuring brightness
in Virtual Reality
applications.

An impressive 205 MHz A/D conversion
bandwidth ensures compatibility with high resolution
and high refresh rate sources for active stereo.
Fast Green Phosphor
CRT projectors offer a
high dynamic range
,
displaying detail from bright highlight areas to dark
shadow areas. Color matching and
color uniformity
is
excellent.
For active stereo applications, where double refresh
rates are required, the persistence and decay time of
the phosphor on the green cathode ray tube (CRT)
must be shortened.
Barco offers active stereo CRT projectors with
fast-
phosphor green tubes
at sizes of 7", 8", 9", and even
12”.

SIM 6
This LCD projector, which is specially
designed for applications in Simulation and
Virtual Reality, offers built-in Warp6
TM
non-linear image mapping technology.
Warp6
TM
enables high-order pre-distortions
electronically with virtually no frame delay,
for use with curved-screen and dome
applications.

Internally Stereo Optimized
By internally polarizing Barco LCD projectors, external
polarizing filters are not needed, thus avoiding the
excessive light loss caused by external polarization. In
this way Barco LCD stereo-optimized projectors are able
to
maintain about 70% of the original light output
.
Barco’s Transport Delay Reduction technology
essentially eliminates the delay between the input
signal and the projected image for
optimal real-time
interaction
with projected images.
