Abstract: A helmet mounted display uses a see-through visor holographic combiner to provide, in the normal field of view of a helicopter pilot, a pair of images derived from an image source such as a miniature cathode ray tube. A source of the video display may be an infrared sensor mounted on an external turret underneath the helicopter. The turret rotates in response to helmet movements so that the pilot is continually provided with a dual image from the CRT display which corresponds with the external scene as visible through the visor.

Abstract: A head-up display for use in a vehicle is provided with a curved combiner which reflects an image from a cathode ray tube (CRT) as collimated rays to a viewing site. A relay lens is positioned between the CRT and the combiner to magnify and transfer the image. The combiner may be a partially-reflecting mirror or holographic optical element or dielectric laminate. Included within the relay lens is a coma-control plate having two-dimensional undulations described mathematically by a two-dimensional power series having odd symmetry in a plane of a tilting of the combiner and even symmetry in the perpendicular dimension. The coma-control plate substantially reduces coma in an image presented for viewing at infinity, the coma being introduced by the curvature and off-axis use of a surface of the combiner.

Abstract: A wavefront sensor (10) for use in determining a phase error of an input beam (16) is disclosed. The wavefront sensor (10) includes mechanisms for obtaining a sample of an input beam (16). A mechanism (18) for splitting the beam (16) into two component beams (46) and (48) is associated with the beam (16). A second mechanism (20) for splitting the two component beams (46) and (48) into four component beams (58), (60), (62) and (64) is associated with the first splitting mechanism (18). A mechanism (26) for detecting the intensity distribution of the four component beams (58), (60), (62) and (64) is associated with the second splitting mechanism (20). A mechanism for determining the phase error of the input beam (16) from the intensity distributions is associated with the detector mechanism (26). Also disclosed is a method for determining the phase error on an input beam (16 ) using the above described wavefront sensor (10).

Abstract: There is disclosed a liquid crystal image projector which is suitable for use as an image source in an aircraft head-up display system. In this application, the projector provides extremely bright and high contrast symbology for the aircraft pilot. More generally, the projector has application wherever a television-type raster and/or calligraphic symbology display is needed. The increase in brightness and contrast ratio is achieved by using a reflector to concentrate light from a light source onto the liquid crystal display cell from whence it is reflected through an optical aperture stop in the reflector to the projecting lens and thence to a viewing surface.
