gbvi simulation applications

gbvi attractions applications


We design and manufacture custom optical blending and light path management solutions for challenging projected display environments including fixed and rotary wing flight simulators, fast-jet simulators, digital planetariums and large scale immersive spaces.

Our optical blending technologies enable system designers and integrators to overcome the hurdles faced when using digital projectors in dark environments such as light leakage, channel overlap visibility, and management of display system contrast and dynamic range.

Visual innovation is at the core of GBvi, and to be innovative means to be creative. We continually prototype new optical blending technologies and often work with unique display setups that lead us to devise increasingly innovative approaches to ensure display perfection.

Chronos Optical Blending

High quality projection systems are built by making sure that everything is right. Designers go to great lengths to configure the display that meets the client’s needs, selecting the best components and carefully configuring them to get the best result.

Seamless image continuity is the goal and calls for the highest quality image blending that is simple to use, yet performs with all scene content and manages any layout complexity with ease.

Chronos optical blending is our primary solution for this challenge and is the highest performance film/glass blend mask technology available in the market. It has been designed to generate a perfectly seamless image across multiple projector channels and is ideal for flight simulation, digital planetarium and theme park dark ride applications. Our highly flexible in-house design tools allow us to design and produce glass or film masks unique to your display for pixel-perfect projection channel edge-blending.

Chronos optical blending has been specifically designed to provide the highest quality blending, taking into account projector characteristics, display design and performance needs. Blends need not be constrained to simple geometry but instead can follow complex curves to allow you to design your system to meet tough requirements.

Chronos Active Optical Blending

Video projectors need to be integrated into a wide range of applications, often meaning the use of ultra-wide-angle projection lenses. As a result, some projectors may need less conventional forms of blending, and that’s exactly what we can provide.


Chronos Active optical blending is a new blend solution that works using an active blend region. Similar to our other blending solutions, a physical structure is added to the projector; however instead of a glass or film mask, a precision-built hard edge is used, moving at such a speed as to be undetectable by eye.

This system eliminates both blurring and colour banding in blend regions, tackling both of the most challenging issues when optically blending wide-angle projectors, whilst still completely eliminating the black level leakage build-up problem that occurs with digital blending.

Chronos Active optical blending will soon to be available to order. Currently tested under single blend configurations, the technology is proven. For further information, and to enquire if Chronos Active optical blending is suitable for your integration, please contact us.

Chronos Rewind

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; i.e., they require removal of the blend masks to enable alignment and calibration to take place.

Chronos Rewind is our dedicated solution that allows for these AA systems to be integrated alongside our Chronos optical blend masks as part of multi-channel projected displays.

Designed for use with a broad range of digital displays, Chronos Rewind uses 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.

Why Optical Blending?

Optical Blending is applied to the full light output of each projector and is the only fully effective method of cleaning up the unwanted projection channel overlap region in multi-channel displays. Our solid engineering approach allows us to understand and manage the complex light behaviour to create seamless blend regions, even in the most demanding of display configurations. This is especially critical when building synthetic environments, such as in the world of full-mission simulation and training.

There are many other benefits of optical blending:



“IDSI has a solid relationship with GBvi – they consistently provide us with engineering services and first-class support that extend above and beyond what they’ve been contracted to deliver.
