Stereoscopic Viewing
We live in a three-dimensional world. The human visual system can process
the slightly different views of the world and translate the views into the
perception of depth. This process is called stereopsis.
In the last two centuries much effort has been devoted to the reproduction of
depth perception, primarily with photography and more recently with
computer graphic images.
Stereoscopic/3D viewing can help a viewer make faster, more accurate, and
more enjoyable interpretations of imagery. The SD2320W StereoMirror™
monitor, in particular, creates an unprecedented level of stereo/3D viewing
quality and viewer comfort.
Stereo viewing is useful for
the following applications:
•Photogrammetry and
remote sensing
•Geospatial image analysis
•Geophysical modeling
•Molecular modeling
•Computer games
•Oil and gas exploration
•Architecture and mechanical
design
•Stereo photography or
videography
•Medical imaging (not as yet
FDA 510(k) approved)
•Surgical planning
•Teaching of anatomy
•Simulation
•Complex data analysis
For some individuals, prolonged use of any stereoscopic monitor
may cause discomfort. Take a break from stereo viewing if you
sense eye fatigue. Individuals who are unaccustomed to using
stereoscopic 3D monitors may require a period of adaptation.

StereoMirror™ Technology
A StereoMirror™monitor consists of two AMLCD (Active Matrix Liquid Crystal
Display) units, oriented at a 110º angle and mounted on a specially designed
stand. A passive beamsplitter mirror bisects the angle formed between the
two monitors, and there is a fine mechanical adjustment for the mirror angle
between the two displays. One side of the glass mirror has a reflective
coating, and the other side has an anti-reflective coating to minimize
secondary reflections. The mirror has been treated with a hard top
coating to accommodate cleaning.
In general, the objective of a stereoscopic display is to efficiently present a left
eye image solely to the left eye while the right eye image is directed to the
right eye. This allows the human visual system to merge the two images and
results in the perception of
depth, or stereopsis. In the
StereoMirror™design this
stereo separation is
achieved using the
principle of conservation
of polarization.
Liquid crystal displays
operate based on the
ability of liquid crystal
material to modulate
plane-polarized light.
The two AMLCDs in the
SD2320W model have
been manufactured so
that the polarized light
emitted from the top monitor is 90° rotated from that of the bottom monitor.
The image from the lower monitor is seen through the mirror, as shown in the
illustration above. When stereo pair images from the two monitors are
viewed through crossed-polarizing glasses (glasses with polarizing films
mounted on the eyepieces with their planes of polarization at a right angle to
one another), the user only sees the left eye image with the eyepiece having
the 0°-oriented polarizer and the right eye image with the eyepiece having
the 90° polarizer. Light with a perpendicular polarization is not transmitted.
The result is a single, fused stereoscopic image.

SD2320W | 3 | User's Guide
A block diagram describing the process of driving a StereoMirror™monitor
with a computer is shown in the illustration below. The left eye and right eye
images are sent to their respective AMLCDs independently and without any
special treatment (with the exception of accommodating for the fact that
the upper monitor is seen in a mirror; see discussion below). Presenting
the stereo pair of images requires a setup or software application that
accommodates dual-monitor stereo viewing. No additional modification
is needed for use with the StereoMirror™monitor design.
Any software application that uses the OpenGL quad-buffered stereo features
is compatible with the StereoMirror™. Quad-buffered stereo is a feature of
the OpenGL 3D graphics library that allows an application to define two
separate right/left eye viewpoints instead of the normal single monoscopic
viewpoint. The two viewpoints are defined to give the correct parallax
separation for the
proper stereo effect.
Once the two
viewpoints have been
defined the 3D scene
is rendered identically
for each of the two
viewpoints. Many
commercial 3D
applications already
have stereo viewing
modes using the
OpenGL stereo
features.
Since the upper
display of the monitor
is seen in reflection, a
mirror-flip operation
must be performed
on that data path. In
the current product
this is accomplished
using an auxiliary signal processing board in the data path to the upper
monitor. Driving a StereoMirror™monitor is identical to driving a pair of
projection displays used to show stereoscopic images with crossed polarizers
in the two separate light paths. An off-the-shelf, dual-output graphics card
is employed to drive the two monitors, again with no special preparation.

Getting Started
Read all instructions before assembling the monitor. Improper assembly can
result in damage to the display components.
Assemble the unit
1. Remove the bottom
monitor assembly from
the shipping box and
place it on a sturdy table
or desktop. To keep the
display surface clean,
avoid touching the
screen.
2. Remove the top monitor
assembly from the
shipping box. Remove
the cover of the
cable management
compartment.
3. Slide the aluminum
flanges of the upper
assembly into the holes
on the cross bracket of
the bottom monitor
assembly until fully
seated. Continue to
support the top monitor
assembly and tighten
the four thumb screws.

SD2320W | 5 | User's Guide
4. Thread the cables from
the top monitor through
the rectangular hole in
the cross bracket.
5. Replace the top and
bottom cable covers,
if desired.
6. Remove the beamsplitter
from the shipping case.
With the StereoMirror™
logo oriented to the
lower right, insert the
pins located on either
side of the mirror frame
into the corresponding
slots on the mirror
support arms. The pins
should rest in the fully
forward position of the
mounting arm slots.
