Abstract: Low light level or night vision apparatus, and particularly goggles, having an objective lens to focus incident light on to an image intensifier and a magnifier enabling an observer to view a magnified version of the intensified image includes a wavelength selective filter with a hole or aperture through which light of other wavelengths can pass, the wavelength selective filter or means associated with the hole or aperture being arranged to have a focussing effect so that light from a distant scene or object of a wavelength passed by the filter can be properly focussed on the image intensifier, and light from a near scene or object passing through the hole or aperture can simultaneously also be properly focussed on the image intensifier, so that either or both images can be viewed in a focussed condition without adjustment of the apparatus.

Abstract: This invention provides a head up display apparatus particularly for use by the pilot of an aircraft including a cathode ray tube to display visual information to the pilot, means for mounting the cathode ray tube on the head of the pilot and a combiner also mounted on the pilot's head to superimpose an image of the displayed information on the pilots view. The apparatus includes a visual information relay system with a visual information source and display means arranged to view the visual information source and operatively connected with the cathode ray tube to display the visual information so viewed. The relay system includes a component arranged to be mounted at a fixed position and a component arranged to be mounted on the pilot's head so that a change of angular position of the pilots head produces a change of position of the visual information relative to the display means and a corresponding change of position of the display of the information on the cathode ray tube.
