This demonstrator Helmet Mounted Display has a complete day and night capability. The binocular optical system provides a fully overlapped 35°field-of-view. The helmet has two 25mm CRTs, which can project an image into each eyepiece (similar to the Cats Eyes™ optics) and this image will overlay the direct view of the outside world. There are image intensified cameras located at each side of the helmet from which a night time image can also be projected into the eyepieces and combined with symbology as required. The HMD is a modular design in which the an inner helmet shell is form-fitted to the pilot for comfort and an outer shell upon which are mounted the electro-optical units appropriate for the planned mission. This outer module forms the front area of the helmet surrounding the face and includes the visor. INVS was the top of a range of helmet systems called Knighthelm™ which started with a simple monocular sight through to the full INVS. The system was used as part of the US Navy's I-Nights technology-evaluation programme.
