I/ITSEC 2017… Until Next Year!

gbvi iitsec chronos greyscale

While the show finished just a little over two weeks ago, I/ITSEC 2017 seems like an age back! 

For the first time GBvi exhibited in its own booth. While small in floorspace (10’ square) we’re confident we got the message across – we do optical blending!

Two Barco FS70 projectors, kindly loaned by Barco for the show, cross-fired onto a simple cylindrical screen, 90° across, with a Chronos optical blend between them.

Our new Chronos Greyscale plates were fitted to compact frames, interfaced to the Barco front support points via a lightweight framework.  At risk of being immodest, the blend was perfect and we received many compliments to that effect.  We developed Greyscale to address the challenge presented by laser phosphor light sources and higher projector pixel counts, both of which push the trade-offs harder when using our patterned masks.  Not to say that patterned masks are dead – they still offer excellent performance and sometimes represent the only high-quality option for some projectors such as 20K Lumen 3-chip units – but we now have another arrow in our quiver, so to speak.

So far as what else we saw at the show, we struggled to get off our booth to find out!  From a displays perspective there were several excellent systems on show, including those from IDSI (on multiple booths), Esterline, domeprojection.com and Q4.  The projector manufacturers also showed their latest and greatest, including 8K devices from JVC and Digital Projection and exciting new LED-illuminated projectors from Norxe and Barco. Apologies to any that we have missed – time was very limited this year…

However, it seems very likely that you’ll see us at I/ITSEC again in 2018.

Season’s Greetings and Wishes to all the Simulation & Training community!

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.

David Cotterrell’s 2nd Exhibition of Mirror III using GBvi’s VOID comes to close at Danielle Arnaud, London

For his fourth solo exhibition at the gallery, David Cotterrell presented three works from the Mirror project: a series of two-screen works produced in collaboration with Ruwanthie de Chickera at London’s Danielle Arnaud Gallery.

The travelling exhibition was open from 25 February to April 1.

Mirror III: Horizon examines what might transpire between two strangers if their communication was reduced to the language of lights. Filmed in Malta, set against the dramatic edges of the island’s stunning coast and contextualized by the island’s deep historical experience of visitors who arrived repeatedly by sea, the installation draws on the fluctuating paranoia of the current refugee crisis. Mirror III examines what might possibly be communicated between strangers if their words were reduced to beams of light and their faces need never be revealed.

The art installation comprises two VOID installations by GBvi, each presenting video media of a Pakistani guard communicating with the other in the secondary VOID. A suspended dome speaker above the installation ensures visitors only experience both sight and sound when underneath the audio and between each of the VOID stations.

VOID, an infinity display experience for educational spaces, attractions and themed experiences, uses special display techniques and light path management to create extreme depth cues and illusions of distance – so that viewers and audiences are provided with a sense of peering into space.

“It’s very difficult to transfer the sensation of place into reality. People can’t understand or recreate this experience from an illustration or image alone and we wanted to generate a sense of emotion and understanding from this installation. The VOID allowed us to do just that.” explains artist David Cotterrell.

“It was important that visitors became fully immersed and engaged with the media. We will continue to use this technology and refine how we apply it in future installations to continue innovating with depth cues and immersion in art.”

Available in a range of size, brightness, projection performance and playback configurations up to ultra-high contrast 4K, VOID is built to deliver realistic, immersive experiences.
