A volumetric imaging apparatus is energizable to form an image onto a display surface as an input to a monocentric catadioptric imaging apparatus having a light path for image-bearing light from the display surface, wherein the light path extends substantially symmetrically to a vertical plane that extends through a curved relay mirror and a curved primary mirror. The monocentric catadioptric imaging apparatus has reflective surfaces to fold the light path between the curved relay mirror and the curved primary mirror to condition the distribution of the image-bearing light in a horizontal direction. The light path of the monocentric catadioptric imaging apparatus directs light from the curved primary mirror toward a light input surface of a vertical pupil expander that has a light exit surface that is substantially orthogonal to the vertical plane. The light exit surface directs light through a free-form corrector for convergence and toward a windshield for display.

Pupil-expanded biocular volumetric display

In an en-route navigation system such as for a vehicle, an image of a cable is presented as a navigation object in a head-up display to indicate a route that the vehicle should follow. The head-up display may comprise a projection screen, light projector apparatus configured to project one or more images onto the projection screen, viewing optics and a computer, wherein the projection screen is moveable under control of the computer in such a way as to adjust positions of the projection screen and to thereby adjust the distance between the projection screen and the viewing optics during at least a portion each of a succession of refresh periods.

Head-up display

An apparatus and method for displaying a virtual map image slightly above the line of sight of a driver of a vehicle. The apparatus and method provide the virtual map image that is in a reflective relationship with the surrounding terrain thereby providing a map that is continuously in the same general azimuthal relationship to the driver as is the surrounding terrain. The virtual map may be scaled or distorted to provide information to a driver concerning distant objects and locations that would not ordinarily be available on heads-up map of the surrounding terrain.
