Abstract: Image-intensifying devices (for example, glasses, goggles, etc.) suitable for certain commercial and entertainment applications by virtue of their light weight, small size, and economical production are disclosed. In one embodiment, input light passes through an Amici reflector, which is used to adjust the orientation of the intensified image to register it with the real world. In another embodiment, input light passes through at least two Amici reflectors, which are used to adjust the orientation of the intensified image to register it with the real world. In alternate embodiments, at least one Amici reflector folds the light at a non-perpendicular angle and/or input light is rotated by an angle other than (180°). Other embodiments include a field-flattening lens disposed in front of an image intensifier. The intensified image is then sent through a projective lens assembly to reach the viewer's eye.

Abstract: Apparatus for detecting airfield light emitters, the apparatus including a plurality of light detection cameras, each detecting at least one respective waveband of electromagnetic radiation within the electromagnetic spectrum, each of the light detection cameras producing a plurality of respective spectral images, and a processor coupled with the light detection cameras, thereby generating a multispectral image of the airfield light emitters from the spectral images, the multispectral image including a multi-dimensional set of spectral values, wherein the processor further determines which combination the multi-dimensional set of spectral values corresponds with a plurality of distinct light emission characteristics of the airfield light emitters by identifying a particular spectral signature corresponding to the multi-dimensional set of spectral values, wherein the processor produces an enhanced image from those spectral values of the multi-dimensional set of spectral values which correspond to the determine

Abstract: System for improving audiovisual communication, the system including a line of sight determining system for determining a user line of sight of the eyes of a user, and an image display system coupled with the line of sight determining system, the image display system displaying a supplementary image for the eyes, and controlling a property of the supplementary image and of a scene image, according to the determined user line of sight.
