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
The StereoMirror monitor
• 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

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.

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.

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.

Select a graphics card
The SD2320W unit requires a dual-output graphics card to drive the two
monitors with a DVI signal. For professional applications that use OpenGL
quad-buffered stereo, the graphics card should support OpenGL stereo as
well. Typically, the two monitors should be in clone mode for these
applications.
There are several compatible graphics card families. The Matrox® Parhelia™
line, the nVidia® Quadro™ FX line, and the 3Dlabs® Wildcat Realizm™ line have
all been tested and are compatible. Matrox® offers the Parhelia Precision SDT
card which incorporates the image inversion functionality of the mirror-flip
PCI card. The nVidia® GeForce® line offers several dual-DVI output graphics
cards that work well for PC gaming and DirectX® applications.
Install the mirror-flip PCI card
Proper ESD (electro static discharge) handling precautions should
be exercised when installing the mirror-flip PCI card. Consult the
computer manual for the installation procedure on graphics cards.
Because the viewer will see a reflection of
the top monitor, this image needs to be
flipped on the horizontal axis. A mirror-
flip PCI card is included with the SD2320W
unit. Plug this card into a free PCI slot in
your computer. There are no drivers to
load with the card.
1. Remove the blank bracket from
an available PCI slot.
2. Insert the mirror-flip PCI card into
the slot, align the connector pins,
and press the board down until it is
firmly seated.

Connect the cables
The SD2320W unit comes with one 6-foot DVI cable, one 12-foot DVI cable,
and one 14-inch DVI cable.
1. Plug one end of the 6-foot DVI
cable into the primary port of
the dual-channel DVI graphics
card. Plug the other end into
the bottom monitor of the
SD2320W unit.
2. Plug one end of the 14-inch DVI
cable into the secondary output
of the dual-channel graphics
card. Plug the other end into
the input port (labeled “IN”) of
the mirror-flip PCI card.
3. Plug one end of the 12-foot DVI cable
into the output port of the mirror-flip
PCI card (labeled “OUT”). Plug the
other end into the top monitor of
the SD2320W unit.
Short DVI cable installed.
The two monitors must be connected with an off-the-shelf video
cable to comply with FCC regulations. Ferrite-core interface
cables are provided. This device will not be in compliance with
FCC regulations when a non-ferrite-core video cable is used.

Connect the power cords
Two power cords shipped with the unit. Use only the power cords supplied
with the unit.
1. Plug the 10-foot cord into the AC power jack of the top monitor. Plug the
6-foot cord into the bottom monitor. Then plug the power connectors
into a grounded outlet.
2. Turn on the soft power switch located on the front bezel of the two
LCD monitors.
3. Power up the computer.
Check the alignment
Although the SD2320W unit is aligned during manufacturing, it may require
realignment after reassembly at your site. There are two fine adjustment
screws located on the mirror support arms. Rotating these screws raises or
lowers the beamsplitter mirror. Adjust the screws so that the corners of the
reflected image of the upper monitor are aligned with the corners of the
transmitted image from the lower monitor.
You may want to use a test image during the alignment process. A sample is
Perfect alignment between the two images is not required for stereo viewing.
The human visual system is typically adept at "fusing" two images that are
slightly shifted relative to each other. This is especially true for horizontal
alignment. In a careful manner, try to achieve vertical alignment as closely as
possible. Coarse vertical misalignment can cause eye fatigue or headaches
since you eyes are accustomed to seeing stereo images from the same
vertical position.

Product Use
Operating in 2D mode
Your SD2320W unit can operate
either as a 3D stereoscopic monitor
or in the standard 2D mode. There
are two options to convert to 2D:
• Simply turn off the power to one
monitor.
• Lift the mirror and slide it into the
locked, upright position.
To return to 3D/stereo, simply
reverse the procedure.

User controls and OSD menu
The two monitors have a soft power switch in the center of the bottom bezel.
The switch has a dual function: the control for turning the monitor the on or
off and the LED indicator of monitor power status. When the LED is green, the
power is on. When the LED is amber, the monitor is in power-saving mode.
The Menu (M), Select (S), up
arrow (c) and down arrow (d)
can be used to control the On-
Screen Display menu. Press

menus. Choose the adjustment items by pressing the Select button. Adjust
the value of the adjustment items by pressing the up or down arrow buttons.
After a period of inactivity the OSD menus will automatically disappear.
The two monitors have an OSD menu that allows control of the brightness,
contrast, and color settings. The adjustment of the brightness setting is not
a direct increase or decrease to the overall luminance, but a driving voltage
adjustment of the LCD panel. In other words, setting the brightness to
0 (zero) does not reduce the luminance to 0 cd/m2.
NOTE: Changing the Brightness setting can reduce the number of discernable
gray levels.

System Care
Monitors. Turn off the monitors before cleaning. Use a dry, soft cloth, clean
room wiper, or compressed air when cleaning the LCD panel surface. A soft
cloth moistened with water and/or mild detergent can be used to clean the
display housing and stand. Do not touch the LCD panel surfaces with sharp
or hard objects. Do not use abrasive cleaners, waxes, or solvents for your
cleaning.
Mirror. Use a dry, soft cloth, clean room wiper, or compressed air when
cleaning the mirror surface. A soft cloth moistened with glass cleaner, water,
and/or mild detergent can also be used to clean the mirror. Do not touch the
half-mirror surfaces with sharp or hard objects. Do not use abrasive cleaners,
waxes, or solvents for your cleaning.
Polarized glasses. Use a dry soft cloth, clean room wiper, or compressed
air when cleaning the polarized glasses. A soft cloth moistened with water
and/or mild detergent can also be used to clean the glasses. Do not touch
the surfaces of the polarized glasses with sharp or hard objects. Do not use
abrasive cleaners, waxes, or solvents for your cleaning.
Software Compatibility
OpenGL®. The SD2320W unit is compatible with OpenGL stereo. An
appropriate graphics card is required to drive the two monitors with DVI
signals. For professional applications that use OpenGL stereo support, the
graphics card should support OpenGL stereo as well. Stereo viewing of
professional applications is typically done in the so-called clone mode where
most of the same information is duplicated on the left and right monitor,
except for the stereo imagery. In other words, the desktop, windows, and
menus are identical, but the bottom monitor shows the left-eye image while
the top monitor exhibits the right-eye image.
DirectX®. The SD2320W unit is compatible with the DirectX® application
programming interface.
Accessories
For repetitive transportation of the SD2320W unit, a reusable, ruggedized
shipping case is available from Planar Systems. The case features a tough
plastic shell, locks, customized foam inlay, and removable wheels.
