IT²EC is Europe’s primary forum where stakeholders from military, government, industry and academia connect and share knowledge about training, simulation and education technologies, taking place at the ExCel exhibition centre in London.
Meet with the GBvi team on our stand (G13) and see our live demonstration of a 2-channel blended projected display featuring the latest generation of GBvi’s Chronos Glass: Greyscale blend plate technology, GBvi’s Atlas-4 projector mounts, a GBvi Chronos Rewind blend mask actuation system, two Norxe P2 laser projectors, a Rockwell Collins EP-8100 IG, and a custom screen from British Mica.
GBvi’s Chronos range (link) of optical blending solutions enable display system integrators to achieve an even black level across multi-channel projection displays, realising the maximum dynamic range and enhancing the perception of life-like imagery.

Chronos Glass: Greyscale
Chronos Glass: Greyscale is the specialist GBvi optical blend technology, compatible with all projector illumination types such as laser, LED and laser-phosphor, and with all projector light outputs and resolutions.
GBvi’s latest greyscale technology has been developed in-house to provide blend masks that have genuine “variable density”, opening up new options and combinations of projector and display types. Artifact-free projected throughput is achieved to result in perfect blends and even hot-spot correction in rear-projected display environments.
Extensive accelerated life-testing has also shown no degradation of the optical behaviour after 20,000 hours of operation.
Use of Auto-Alignment (AA) systems for projection display calibration is becoming universal. While these systems produce excellent results, some benefit from removal of the optical blend masks from the light paths so that unrestricted projected coverage can be sensed.
Chronos Rewind is our dedicated solution that allows for auto-alignment systems to be integrated alongside our Chronos optical blend masks as part of multi-channel projected displays.
This process allows for the blend to be retracted from the lens, auto calibration to be completed, and for the blend mask to be returned to its original, correct position.
GBVI’s Atlas-4 projector mount robustly interfaces a projector to a display system support structure while providing all the necessary mechanical adjustments to optimise projection geometry.
Four Degrees-of-Freedom (4DOF) adjustability provides yaw, pitch and roll rotations that pivot about the projection point and fore-aft translation along the projection axis, significantly easing the bore-sighting process.
Existing Atlas-4 variants offer mounts for Barco, Norxe, Sony, Panasonic and Canon simulation projectors, while high configurability means that other projectors are easy to introduce.
Its small footprint allows it to sit under the projector body without compromising tight projector cluster designs typical in simulator designs.
Front interface points support Chronos optical blending system and the quick-release mount enables a projector to be removed and replaced without disturbing the Atlas core or the optical blend.
