DepthQ® Polarization Modulator TM

Overview

The DepthQ® Polarization Modulator utilizes a unique 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 (50 μsec at room temperature) between polarization states at frequencies from 120Hz to 400Hz.

By actively alternating between two orthogonal polarization orientations in sync with progressive ‘page-flip’ stereoscopic data, matching polarized eyewear can passively block or transmit light to the viewer's eyes at the appropriate moment. Efficient, 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. A standard stereoscopic sync output from your graphics card or video projector should be supplied to the control unit, which uses the input to drive the modulator synchronously.

The modulator is available in two sizes: Small, for projectors with apertures <9.84 x 6.11 cm (3.875 x 2.41

in), and Large, for projectors with apertures <17.15 x 9.78 cm (6.75 x 3.85 in).

The optical window is also very heat-tolerant and can operate at temperatures up to 52 degrees Celsius (125 deg F).

The DepthQ® Polarization Modulator is available pre-configured for circular polarization only.

Polarization

A fast polarization modulator comprises fast switching liquid crystal elements designed to rapidly switch the plane of polarization of incident light. Utilization of a unique combination of separate liquid crystal elements stacked together enables both high polarization efficiency over visible wavelengths as well as fast transition switching speeds between polarization states up to 400Hz. Typical 3D projection operates at 120Hz or 144Hz.

Polarization is available in circular.

DepthQ Polarization Modulator, Circular: - The linear input polarizer on the circular modulator is vertical, 90 degrees. - Matching circular glasses orientation: both eyes have the linear element at 0 degrees, 0/0

General System Requirements

The following are the system requirements for a complete passive polarized 3D projection system.

Polarization Preserving Screen

Use of a polarization preserving screen is mandatory.

3D front projection silver screen manufacturers supported (minimum suggested gain 2.2): Harkness Screens, Severtson Corporation, Stewart Film screen, and STRONG / MDI Screen.

3D rear projection polarization preserving screen supported (minimum suggested gain 1.5): Stewart Film Screen.

Other screens may be used, but performance may be effected.

3D Projector

DepthQ polarization must be paired with a well designed “3D-Ready” 3D projector. DepthQ polarization does not work with standard 2D projectors.

003-Connecting Actuator to Manual Controller

004-Actuator Manual Controller – Down arrow moves modulator in front of lens (towards actuator motor).


005-Actuator Manual Controller – Up arrow moves modulator away from lens (away from actuator motor).

006-Connecting Actuator to Automated Controller

007-Moving Actuator control cable connected to drive motor. The black box contains a latching relay which controls the in and out movement of the modulator. The white cable should be connected to the theater’s show control system. Applying 12v DC momentarily between the silver wire (ground) and the white wire will cause the sled to move towards the motor. Applying 12v DC momentarily between ground and the black wire will cause the sled to move away from the motor. Use a momentary (pulse) contact closure signal.


008-Close up of moving actuator control latching relay, the bare wires of the white cable connects to the theater’s show control system.

009-White cable connects to theater control system. Applying 12v DC momentarily between ground and the white wire will cause the sled to move towards the motor. Applying 12v DC momentarily between the silver wire (ground) and the black wire will cause the sled to move away from the motor. Use a momentary (pulse) contact closure signal.

Polarization Modulator Control Unit Menu System

The following is the menu system for the control unit, which is accessed via a web browser. Please use the included “Ethernet crossover cable” which is used to connect your computer, laptop, or netbook directly to the control units without a network switch.

Network Control

You can monitor operation and change control unit settings by way of a "web page" style interface. To access this page, you need to connect the control unit to your PC through an existing network or directly to your PC (using the supplied cross-over network cable). From your PC, point your web browser to the IP address of the driver to bring up the monitoring and control web page (above).


The control unit network values are shown cycling on the bottom line of the display screen. The IP address is included. If your driver's IP address is 192.168.1.254, then the URL should be http://192.168.1.254

If you do not get a response from the unit try a direct connection to your computer without using any switches or hubs. It is possible your network setup translates the IP address to an improper value.

Configuring Your Computers IP Address

If your computer’s IP address does not already match the first three numbers of the control unit’s IP address, you will need to reconfigure your computers network connection with a proper static IP address. The screen shots below show the process when using Windows 7. The process under Windows Vista and Windows XP is similar.



Web Interface

Below are pictures of the three screens in the Web Interface. A password is required to access the Advanced and Network Settings pages. The username is “admin” and the password is “depthq”.

Explanation of features – Main Settings

Input Frequency

This setting indicates the frequency of the incoming stereo sync signal. Typically this should be a value higher than 100 Hz. On a PC based system, 60 Hz indicates improper graphics card setup. A value of “No Signal” indicates there is no input signal. In this case, check the connection between the control unit and your stereoscopic sync signal source. Also check your graphics card stereo sync setup. On NVIDIA Quadro cards a stereoscopic application must be running and visible in order for a sync signal to be generated. Digital Cinema (DCI) Projectors: The frequency will be 143 Hz or 144 Hz. Trouble Shooting: If the input frequency changes between values like 60 Hz to 120 Hz or 48 Hz to 144 Hz, this indicates stereo sync signal noise. Projector lamps are notorious for creating lots of noise. Be sure to use ferrite core noise suppressors on the input cable. These are included on all cables provided by Lightspeed Design.

Output Voltage

This setting indicates the current voltage of the modulator drive signal. It is factory set around 24V. The value will vary slightly since it is reporting the true measured output.

Trouble Shooting: If the voltage reads a substantially different value than 24V (12V for example) performance will be greatly reduced.

Signal Reversed

This setting establishes the eye coding or “invert state” for the control unit. Set to opposite state to invert the stereo. There are two options: Normal and Reverse.

Normal is equivalent to “L/R” (as seen on the control unit’s display). Yes is equivalent to “R/L”.

Digital Cinema (DCI) Projectors: DepthQ Modulator control unit setting should always be Normal.

Trouble Shooting: If there is excess crosstalk or the 3D image is reversed the above settings are incorrect.

Global Phase Shift

This setting establishes the delay value of the drive signal (expressed in microseconds). This setting is used to optimize the control unit’s synchronization with the projector’s dark time.

The default value is 0µs.


A value of 1500µs means the modulator will change orientation 1500 microseconds after the input signal changes its orientation.

The Global Phase shift setting is very important to the control unit’s perceived performance. Lightspeed generally calibrates this setting while monitoring the projector and signals on an oscilloscope. Please see below or contact Lightspeed for settings for each projector type and model.

Save Settings

When you have completed changes use “save settings”. All values will be permanently stored in the modulator EPROM and used upon power up.

Explanation of features – Advanced Settings

B-Delay

B-Delay is a factory set value and should always be set to 300. Do not change this value unless specifically instructed by Lightspeed Design. Incorrect settings can cause ghosting.

Min. 3D Input Frequency (introduced in firmware version 0.40)

Minimum 3D Input Frequency allows you to set the lower cut off for 3D operation. If the input signal frequency goes below the Minimum 3D Input Frequency, the control unit’s output will be disabled. The default value is 40Hz. When the output is disabled due to low input frequency, the text “L!” is shown on the screen.

Max. 3D Input Frequency (introduced in firmware version 0.40)

Maximum 3D Input Frequency allows you to set the upper cut off for 3D operation. If the input signal frequency goes above the Maximum 3D Input Frequency, the control unit’s output will be disabled. The default value is 500Hz. When the output is disabled due to high input frequency, the text “H!” is shown on the screen.

Description of Phantom Output

The Phantom Output feature allows the control unit to generate its own internal sync signal when it detects the outside stereo sync signal is absent. This can be useful when using a PC as it will allow the modulator to continue to show both left and right eyes after exiting the stereoscopic application. Without this feature one eye will be blacked out when you exit to the windows desktop. Special care must be taken when selecting the Phantom Frequency for single chip DLP projectors since it can interact with the projector in undesirable ways.


Phantom Output should typically be disabled in a cinema environment since you would normally want to be aware of a condition where the stereo sync signal is missing. It can be useful for forcing operation at a specific frequency. For example, if you are shooting colors using a 2D test pattern it may be desirable to force the control unit to operate at 144Hz instead of the 24Hz that the projector would be sending. To do this, unplug the BNC connector from the control unit, set your desired Phantom Frequency and then set Phantom System to “Enabled”. When you are done, be sure to set the Phantom System to “Disabled” and reconnect the BNC cable.

Phantom Output

This setting indicates the status of the phantom output system. “Active” indicates the outside stereo sync signal is absent and the Phantom System is currently in operation. “None” indicates the Phantom System is not in operation (either because Phantom Output is disabled or the outside stereo sync signal is present).

Phantom System

This setting indicates the operation mode of the Phantom System. “Disabled” indicates the Phantom System will not activate when the outside stereo sync signal is missing. “Enabled” indicates the Phantom System will activate when the outside stereo sync signal is missing.

Click the “Enable” or “Disable” buttons to enable or disable the Phantom System.

Phantom Frequency

This setting indicates the frequency at which the Phantom System will operate at. If you wish to change the frequency, type the new value in the box and click the “set” button.

A value of 144Hz tends to work well with DCI Cinema projection systems since it is an even multiple of 24fps. Special care must be taken when selecting the Phantom Frequency for single chip DLP projectors since it can interact with the projector in undesirable ways. You might need an especially high value to eliminate harmonics with the DLP light output.

Save Settings

When you have completed changes use “save settings”. All values will be permanently stored in the control unit EPROM and used upon power up.


Explanation of features – Advanced Settings

DHCP Settings (introduced in firmware version 0.40)

The control unit can have a static IP address or it can request an IP address from your network DHCP server. By default, the control unit has a static IP address of 192.168.1.254.

If you wish to switch to a DHCP assigned IP address, select the “DHCP Client” radio button and then click the “SAVE & NETWORK RESTART” button. This will reinitialize the network portion of the control unit (the main unit does not reboot). Upon start up, the control unit will request an IP address from your local DHCP server.

This IP address will be displayed on the bottom line of the LCD screen. This bottom line also cycles through the other network settings (netmask and port number). This IP address will be the address you need to type into your web browser to connect to the control unit. The computer you are using to connect to the control unit web interface must reside on the same network segment in order to communicate with the control unit. Most often this means the computer IP address should have the same first three numbers as the control unit, with only the last number being different. Note: If the control unit is not able to communicate with a DHCP server it will time out and configure a random static IP address in the 169.254.x.x address space. If you cannot resolve the issue with the DHCP server you may have to configure your computer with a static IP address that matches the first three numbers of the IP address the control unit is showing. The last number must be different from the last number of the IP address of the control unit.


IP Address

These fields both indicate and allow you to configure the IP address of the control unit. Normally it is set to 192-168-1-254. This is the IP address you should type into your web browser to connect to the control unit web interface.

Network Mask

Sometimes referred to as “Netmask”. These fields both indicate and allow you to configure the Network Mask of the control unit. Normally it is set it 255-255-255-0 unless your network requires a different value.

Communication Port

This field both indicates and allows you to configure the communication port that the control unit listens on. Normally it is set to 80 which is the standard for HTTP communication. Note: Be sure to click the “SAVE & NETWORK RESTART” button to apply all changes you have made on this screen. When you click this button, your values will be permanently stored in the control unit EPROM and the network interface will be re-initialized.
