Preview of 'Star Trek Into Darkness' with Christie projection in 'Quad' configuration and Dolby Atmos

This configuration, designed for stereoscopy, uses four digital cinema projectors with a special newly developed lens alignment system that allows a perfectly aligned image of extremely high brightness to be projected.

Coinciding with the premiere at the Dolby Theater in Los Angeles of Star Trek Into Darkness, Christie has carried out for the first time before a mass audience a stereoscopic projection with laser projectors in a 'Quad' configuration. The pre-premiere has also been carried out with immersive sound Dolby Atmos.

This configuration uses four digital cinema projectors with a newly developed special lens alignment system. On this occasion four Christie CP4230 4K DLP were used.

Two of them faced the screen directly, while the other two were arranged at right angles, projecting the light onto two mirrors that channeled it towards the screen. In this way, a system is achieved that is actually the sum of two “Duos” (as we can see in the image configuration) in which two projectors are perpendicular to each other and one of the images bounces off a mirror.

Christie plans to market this 'Quad' projection in conjunction with Dolby 3D.

The objective of the Quad system is to project four images on a screen with completely precise alignment, thus achieving unprecedented luminosity in stereoscopic projections. One of the common problems with this type of multiple projection configurations is that the lenses are so far apart that it is impossible for every pixel on the screen to match. It is possible, for example, to perfectly align the center of the image, but impossible in the edge areas.

This 'Quad' projection system developed by Christie eliminates this aberration and offers sharp, ultra-high brightness images across the entire screen area in 3D projections.
