GBvi to Premier Two New Technologies at I/ITSEC 2017

Sussex, England — 16 November 2017 — GBvi, an industry leader in the development of high performance projector optical blending solutions for out-the-window simulation and training, will be launching two new optical blend technologies at I/ITSEC 2017 in Orlando, Florida, from November 27th to December 1st. On the GBvi stand (#2736), conference attendees can see a live demonstration of two innovative new products – Chronos Greyscale and Chronos Rewind.

GBvi’s Chronos range 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.

Two new product additions to the Chronos range will be premiered for the first time by GBvi at IITSEC with on-stand demonstrations at the show.

Chronos Greyscale

Chronos Greyscale is the new specialist GBvi optical blend technology that addresses the ‘small 4K’ and 8K class of projection systems where some optical trade-offs are most challenging, particularly with laser-phosphor illumination.

Chronos Greyscale is qualified for use with LED and laser phosphor projectors .

Chronos Rewind

“Use of Auto-Alignment (AA) systems for projection display calibration is becoming universal.” Geoff Blackham, founder and managing director of GBvi, explains. “While these systems produce excellent results, some perform best after removal of the blend masks from the light path to enable alignment and calibration to take place.”

Designed for use with a broad range of digital displays, Chronos Rewind addresses this issue, using an actuated platform and simple trigger interface to move the blend mask to and from the projector lens as required in a carefully controlled and precise manner.

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.

Chronos Rewind allows for AA systems to be integrated alongside our Chronos optical blend masks as part of multi-channel displays.

“Our expertise in the field of projection display systems means we can provide an unrivalled service, helping customers with the whole display challenge – not confining our input to the blending alone.” says Blackham.

GBvi’s optical blending technology enables integrators to provide display systems which are free from the visual issues caused by digital blending. This means no ‘double-bright’ overlap regions, and no impact to contrast or dynamic range, as black level infill is no longer necessary to match blend brightnesses.

Chronos has been successfully implemented on WUXGA, WQXGA and 4K single-chip DLP, WUXGA and 4K 3-chip DLP and 4K LCoS projectors, including lamp, laser-phosphor and LED illuminated models.

Geoff’s presentation, titled ‘Optical Blending for Maximising Dynamic Range of Projection Displays‘ will be given at 16:05 on October 4th, 2017 and has a published abstract of:

Quality projection displays for visual simulation have evolved to use mainstream commercial projection devices, which, together with automatic alignment solutions, have dramatically reduced time required for their installation, alignment and maintenance.  However, one bugbear has remained in the form of projector light leakage when displaying dark scene content.  Electronic blending solutions exist that produce excellent results for bright scenes but, for continuous background intensity levels in dark scenes, infill techniques are often applied, which can sacrifice up to 75% of the possible dynamic range. Optical solutions to blending multiple channels can solve this problem, offering the promise to increase the utility and hence value of visual simulation training substantially, yet often this option is not even considered – so why is this?

Optical blending implementations – which place physical masks in the projection light paths – have been around for a long time, but a universal solution for all projector types and scene content has yet to become available.  Many solutions give relatively poor performance that can be tolerated for dark scenes such as those experienced in night training, so are actuated out of the light paths for use with daytime scenes.  These present logistical challenges to simulator users, where a choice must be made as to what “mode” you are training, or some transition must be suffered while the blending system switches mode.  Other solutions cannot withstand sustained light flux without degradation, so again must be actuated, while yet others may cause image sharpness degradation in the blend regions, so must be designed very carefully to limit this impact, particularly with high-resolution projectors.

Included in this presentation will be a review of the mainstream projection technologies and their respective pros & cons, particularly with regard to scene dynamic range and blend implications. This in turn leads to a detailed review of optical blending options, presenting their operating theories and application scope.

GBvi Completes Delivery of Specialist Multi-Channel Optical Blending for European Fast Jet Simulator

Sussex, England — 19 January 2016 — UK-based expert in display technology innovation and multi-channel projector blending, GBvi, has completed delivery of a five-channel Chronos optical blending installation for a European Fast Jet Simulator installation.

The company was awarded the contract by Antycip Simulation in August 2015, after a year-long commercial relationship.

Antycip Simulation markets, distributes and supports a range of commercial software solutions for the modelling, simulation and training communities. GBvi was chosen to provide Chronos, its proprietary high performance film/glass blend mask solution, for a seamless multi-channel digitally projected display.

Antycip Simulation’s requirements detailed display design validation and the specialist need for wide-angle lens compatibility, among other key contract requirements.

Riccardo Rovelli, Area Manager for Italy and Germany, at Antycip Simulation notes, “Antycip Simulation uses GBvi technologies in a range of fast-jet and helicopter simulation applications – their experience, dedication to innovation and exceptional support, help us meet the technical and design challenges clients present us with”.

He went on to say, “It’s critical to our projects, that our technology partners maintain unrivalled levels of accuracy and attention to detail in both system design and delivery. I’m very pleased to say that GBvi is an excellent partner, in these regards, and far exceeded our expectations.”

Geoff Blackham, Founder and Managing Director at GBvi explained, “This was a notably exciting project for us. Our team employed several design customisations including projector alignment boresight pattern generation, specialist mounts, custom blend masks, HUD filter assembly and warp mesh generation. Our engineers were fully integrated as part of the team with Antycip Simulation and on-site at the end client, for successful simulator integration.”

GBvi supported both the projection display and blend installations. A key feature of the Chronos optical blending technology is its fast installation time and full customisation process. GBvi completed blending installation in just one day on this contract – a phase that can typically take several days.

“We were chosen as providers of the highest quality blending system available in the market and for our positive customer support reputation.” Blackham continued. “This successful project illustrates that we offer valuable scope well beyond product supply – we are delighted to have been a part of the installation team on this project.”
