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 SD2620W 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 principle of conservation of polarization.

Operating principle of the StereoMirror monitor

™ design this stereo separation is achieved using the

Liquid crystal displays operate based on the ability of liquid crystal material to modulate plane-polarized light. The two AMLCDs in the SD2620W 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 crossedpolarizing 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 90°-oriented polarizer and the right eye image with the eyepiece having the 0° 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 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 identical 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. Loosen the two screws on the cover of the cable management compartment and remove the cover.

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.
