DepthQ Polarization Modulator

The DepthQ® Polarization Modulator utilizes a unique control methodology and combination of separate liquid crystal elements bonded together, enabling both high polarization efficiency over visible wavelengths from 400 to 750 nm (predominantly achromatic spectral response) as well as fast transition switching speeds between polarization states (0.05 ms) at frequencies from 96 to 400Hz.

By actively alternating between two orthogonal polarization orientations in sync with progressive left/right 144Hz 'triple-flash' stereoscopic cinema projections, matching polarized eyewear can passively block or transmit light to the viewer's eyes at the appropriate moment. Efficient, symmetrical, 50 microsecond high-speed switching between the eyes ensures bright, low-crosstalk, flicker-free operation.

The system includes both the liquid-crystal modulator as well as its control unit, plus hardware which mounts the unit to the front of your projector, and an actuator to move the modulator in and out of the projection path (for switching between 2D and 3D). Sync output from your projector's GPIO port is supplied to the control unit, which then conditions the signal to match the modulator's required input.

The modulator supports projectors up to 22,000 lumens and can take the heat from either 3kW or 4kW lamps. A combination of passive and active cooling at the optical window is designed to keep the liquid crystal elements cool - both to increase the quality of the projected 3D image and to extend the polarizer lifetime.

The DepthQ® Polarization Modulator for 3D digital cinema has been approved by Walt Disney Studios Motion Pictures, and is available with circular polarization only.

DepthQ® Polarization Modulator

The Best from Active and Passive systems together!

When combined with a silver screen, the new DepthQ® Polarization Modulator allows your digital cinema projector to display stunning stereoscopic 3D films, viewable using inexpensive passive glasses. Paired with projectors up to 18.5K ANSI Lumens, DepthQ® provides a spectacular 3D experience for screens up to 13.7m (45ft).

DepthQ® meets Hollywood's demanding image quality standards by precisely and efficiently varying the polarity of light passing through it, in perfect synch with the "triple-flash" of left and right eye images from digital cinema projectors.

Beyond that, an unprecedented 50 microsecond symmetrical switching time between the eyes ensures bright, low-crosstalk operation. In general, this switching time actually occurs faster than the smallest dark interval setting currently available in digital cinema projectors...so when they 'catch up', even brighter 3D images will result!

The new DepthQ® Polarization Modulator has been approved by Walt Disney Studios Motion Pictures.

DepthQ® HDs3D-1

Professional High Definition 3D Projector

The DepthQ® HDs3D-1 high-definition 3D projector is the 3rd generation of Lightspeed Design's patent-pending portable stereoscopic projectors, offering superior contrast, synchronization and crosstalk ("ghosting") for 3D professionals.

These projectors leverage nearly two decades of professional 3D knowledge and expertise to deliver the highest-quality, most satisfying and hassle-free 3D experience possible - right out of the box.

New to the HDs3D-1 is higher brightness (2700 lumens in 3D mode), an all-digital HDMI input path for unsurpassed clarity, and start-up/shut-down times half that of previous models.

Additionally, these bright, professional-level 3D projectors can easily display 10 ft (3 m) wide 3D high-definition images using the latest Texas Instruments DLP® and BrilliantColorTM technologies - for wall-filling imagery with stunning colors and a 2100:1 contrast ratio, at a truly unprecedented level of price-performance.

  • Professional – Superior Contrast and Synchronization
  • Digital – Digital HDMI or analog VGA input
  • Bright – 2700 ANSI Lumens in 3D mode
  • Quality – Flicker-free, 120Hz 1280x720 3D
    with DLP® BrilliantColorTM technology
  • Portable – Small & only 7 pounds, fits in the overhead bin
    and takes less than 5 minutes to set up
  • Versatile – Work live in 3D-enabled applications;
