Active circular light polarisator

Click to enlarge

The active polarisationfilter allows a 3D projection on polarisation base with just one 3D Ready DLP-projector.

This 3D projection technique combines the advantages of one-projector-projection with the polarisation-process.

Costs of the system and expenditure of time caused by the installation get diminished, because the dual-projector-rack and the adjustment of the two projectors do not apply.

You can use light plastic- or paperframed glasses, what’s very useful for public presentations and provides optimal performance, but can also be used for home theater users.

This technique operates with a timemultiplex method, which projects two images for the eyes chronologically in series, the active polarisator changes the direction of the polarisation per image, by what the passive polarisation glasses of the users let just pass the appropriate image for the right eye.

The 74 x 74 mm active ploarisationfilter is fitted into a 120 x 107 mm frame. The driver electronic consists of a Dongle with a VESA 3 Pin. Sync input and an RCA output to the polarisation panel.

The Dongle has a switch for the conversion of the phase, which interchanges the allocation of the eyes for the images and two rotary-switches with 10 positions to adjust the sync signal to the image of the projector.

The use of the silver screen is nescessary.
