TLDR
In this paper, an optical display for an aircraft flight simulator or other vehicle motion simulator, providing a wideangle, collimated visual display for one or more observers, for example trainee pilot and co-pilot, is described.Abstract:
Visual display apparatus, particularly for an aircraft flight simulator or other vehicle motion simulator, providing a wideangle, collimated visual display for one or more observers, for example trainee pilot and co-pilot. The apparatus includes an optical projector, a large concave mirror and a curved optical element between the observer and the mirror. The projector projects an image onto the optical element, the image being viewed after reflection, and collimation, by the mirror. The optical element is of special construction so that it serves as a projection screen but permits reflected light from the mirror to pass therethrough. In one particular construction, the optical element is a spherical surface having strip-like diffusing and deflecting grooves with intermediate window strips.read more

Wide field of view head-up display system
TL;DR: In this article, a head-up display (HOVD) is used to display high-resolution images on a sub-region of the projection surface (604 ) that has a optical relay ( 650 ) disposed therein.

TL;DR: In this paper, a scanned light display system includes a light source operable to emit light and a curved mirror positioned to receive at least a portion of the light, and an optical element is configured to substantially collimate the reflected light.
Patent
Spherical projection system
TL;DR: A spherical projection system as mentioned in this paper includes a spherical rear projection screen assembly of an extent such that a viewer can see projected images in any viewable direction, a plurality of image projectors which cooperate to project portions of a continuous panoramic scene onto all the viewable surfaces of the screen assembly, sets of mirrors to reflect the images onto associated areas of the space assembly, and an opaque enclosure which houses the screen, mirror sets, and image projector.

Display system for multiviewer training simulators
TL;DR: In this article, a display system is described which employs multiple holographic elements for selectively reflecting images from separate projectors (P1, P2) to one or more distinct viewing volumes (V1, V2).
Patent
Imageing element and display
TL;DR: In this article, a plurality of unit optical elements for reflecting light on one or more mirror surfaces arranged perpendicularly or at an angle nearly perpendicular to the element face are disposed to constitute an optical imaging element.
