Abstract
A helmet mounted binocular goggle night vision viewing system comprising two independent night vision viewing arrangements, one for each eye of a wearer of the helmet, supported from above the face aperture of the helmet, each viewing arrangement comprising an optical projector arranged to project an intensified image of a scene ahead of the helmet wearer downwardly to a body of light refractive material in front of the wearer's eye having parallel flat fore and aft surfaces spanned by an upper surface via which light from the projector enters the body for reflection towards a curved partially reflective, partially transmissive surface within the body by which the light is reflected back towards the aft surface for transmission therethrough to the wearer's eye, thereby to provide the wearer with a view of the projected image superimposed on his view of the scene ahead through the body.
