Notes:

This is a metal badge with a pin fastener at the rear. It shows the Marconi Avionics logo with the name ‘Cats Eyes’ in green with a cat’s face below given the same green eyes. The face is used on the related Brochure D0023. Cats Eyes was a Night Vision Goggle system first seen around 1982 and the Brochure dates from this early design. However, the NVG design was much improved in later years seeing service with the US Marine Corps. The RAA has two of these badges

The Company in common with most organisations has a wide range of items promoting the Company name as a form of advertising. The range extends from  'cheap and cheeful'; the sort of thing that would be on the Stand at an Exhibition like the SBAC Farnborough Show. The young visitors love collecting these items along with pictures and Brochures. Such items would include the following:

Stickers, Carrier Bags, Furry Bugs, simple aircraft assembly kits, Cardboard Head Up Display, Drinks Mats. Sometimes a collection of items is put together in something like a Pouch or presentation bag.

A more up-market offering, of better quality, might include:

Mugs, Pens, Key Fobs, Tape Dispensers, Magnifying Glasses, Model cars or the Hybrid Bus, Penknife and Pens.

The top range gifts are usually presented to important visitors or taken on visits to customers and these might include:

Executive Toys, Paperweights, Business Card Holders, Wallets, Clocks, Calculators, Engraved glasses and Glass blocks with a contained model and legend (BAE Systems liked to produce glass Globes to illustrate the global reach of the company). A rather special gift has been a Hologram of a coin.

Ties have been a regular gift in the days when they were regularly worn and were presented as recognition of achievement or membership of a group or ‘club as well as being a promotional gift. Employees for example will be encouraged to wear a T-Shirt with a Corporate Logo which gives a corporate identity. 

The RAA includes items of this type acquired from Suppliers and visits to Customers.

 

In July 1981  work was started in the Company Research Laboratory, FARL, to investigate design concepts for Night Vision Goggles for fixed wing aircraft application. The Cats Eyes™ NVG system allows for the combination of both a direct visual and an intensified image to be presented to the pilot's eyes. The two images are combined in a 1:1 relationship and complement each other. The Head-Up Display is seen through a direct visual path, and it is not degraded by unnecessary image intensification as it would be with conventional NVG systems. Additionally, the direct vision path through the optical combiner arrangement makes monitoring of cockpit displays and instruments considerably easier while the ability to scan either side of the combiners enhances peripheral vision and ensures better spatial awareness. The direct vision path also removes problems normally associated with light to dark transitions as the intensified image becomes progressively more noticeable as the direct visual image fades.  The FLIR image on a HUD is viewed directly and by a simple IR tracker the Image Intensifiers can be turned off whenever the HUD image comes into the field of view of the Cats Eyes™.

The folding of the Cats Eyes™ optical system results in a circular 30 degrees field-of-view with some clipping of the image in the lower right and lower left.   The system is compact and rugged, and the restrictions on head mobility imposed by the depth of conventional NVG systems are avoided. While the system incorporates a single handed quick release mechanism for the helmet interface, it can be configured to include an automatic separation system on ejection and designed growth will enable it to accept the latest image intensifier technology as it becomes available. The benefits of the system have been extensively proven in low-level night attack flying trials, which used a fully integrated NVG-compatible cockpit and Forward Looking Infra-Red (FLIR) generated head-up display imagery, together with a head-down multifunction display.

In March 1982 a demonstrator was produced which had a field of view of 45deg horizontal and 30deg vertical and achieved all the design targets with a low head mounted mass and minimum moment about the pilot's head. Favourable evaluation lead to the manufacture by the Airborne Display Division of flyable prototypes. A story from the early trials was that a set of Goggles was sent up to the Harley Street Institute of Opthamology for tests on the peripheral vision while wearing them.

Cats Eyes™ NVG were sold to the US Marine Corps for the AV8-B and performed well in combat during the 1990-91Gulf War.
