摘要： A vehicle simulator having a projection system for projecting a generated scene and symbology onto a common viewing screen. Tracking apparatus is provided for providing position and/or angular orientation signals representative of the eye of a person viewing the projected scene and symbology. An image generation system is included for generating the scene and symbology for the projection system, such scene and symbology being generated as a function of the position and/or angular orientation signals provided by the tracking apparatus. Such symbology is representative of symbology produced by a head-up display. The image generation system generates the scene and symbology with characteristics which simulate vignetting and/or occulting effect characteristics of the head-up display. The OTW scene and symbology are projected onto a screen and are co-located while the image generator, base or data of the eye position of the user, produces the symbology to simulate the collimation, vignetting and occulting effects of the HUD optical type used in the vehicle that is simulated.

摘要： A focusable virtual image display system employing a focusable image source such as a cathode ray tube and imaging optics to provide a virtual image. The virtual image is viewable by a user and its effective range may be changed without changing the apparent field of view or resolution. By placing the focus point of the imaging optics at the design eye, the image source is moved backwards and forwards, thus effectively changing the range of the virtual image observed by the user without changing the apparent field of view or resolution. The present invention allows the user to adjust the focus position of the virtual image of the image source by moving it relative to the imaging optics, while maintaining the size and resolution of the image. If the user wants to move the image further away, when the image source is moved, the imaging optics moves the virtual image further away and magnifies the image such that the angular field of view stays the same. The user cannot distinguish between the sizes, although the focus will be more comfortable for a particular accommodation range. The relative cost of the virtual image display system is relatively less expensive than large screen monitors due to the nature and complexity of the smaller components. By including a focus adjustment mechanism, the focusable virtual image display monitor has an added feature that a conventional large screen monitor does not provide.
摘要翻译：采用诸如阴极射线管和成像光学器件的可聚焦图像源的可对焦的虚像显示系统来提供虚像。虚拟图像可由用户查看，并且可以改变其有效范围而不改变视野或分辨率。通过将成像光学元件的焦点放置在设计眼睛处，图像源被向前和向后移动，从而有效地改变用户观察到的虚拟图像的范围而不改变视野或分辨率。本发明允许用户通过相对于成像光学元件移动图像源的虚像来调节焦点位置，同时保持图像的尺寸和分辨率。如果用户想要将图像移动得更远，当图像源被移动时，成像光学元件将虚拟图像进一步移动并放大图像，使得角度视场保持不变。用户不能区分大小，尽管对于特定的住宿范围来说，焦点将更加舒适。由于较小组件的性质和复杂性，虚拟图像显示系统的相对成本比大屏幕显示器相对较便宜。通过包括焦点调整机构，可聚焦虚拟图像显示监视器具有常规大屏幕监视器不提供的附加功能。

摘要： An optical arrangement that provides a telecentric helmet mounted display optical system. The optical arrangement comprises an image source including a faceplate wedge attached to a liquid crystal display, such as an active matrix liquid crystal display, for example, that is illuminated with collimated fight. The output image is used as a light source for an off-axis or on-axis reflector used to produce an output image. The faceplate wedge corrects the anamorphic distortion exhibited in the off-axis reflector and directs the light energy into the off-axis entrance pupil of the reflector to maintain high uniformity over the exit pupil without sacrificing brightness. More particularly, the present invention comprises the input light source, and the liquid crystal display that is illuminated with collimated light from the light source. The faceplate wedge is optically coupled to the liquid crystal display, and the reflector is optically coupled to the faceplate wedge for producing an output image. The faceplate wedge corrects for anamorphic distortion exhibited in the reflector and directs light energy into an off-axis entrance pupil to maintain high uniformity over the exit pupil without sacrificing brightness. The reflector may comprise an off-axis or on-axis portion of a parabolic reflector. The optical arrangement may further comprise a collimating lens disposed between the liquid crystal display and the input light source. The collimating lens may comprise a Fresnel lens. In an off-axis version, the optical arrangement may further comprise first and second planar reflectors disposed between the input light source and the collimating lens, and a negative lens optically coupled to an output surface of the faceplate wedge. In an on-axis version, the optical arrangement may further comprise a beamsplitter optically coupled between the faceplate wedge and the reflector.

摘要： A compact, inexpensive and mass-producible optical display system for an automobile creates a highly visible and sharp, high contrast and pleasing, multi-color magnified virtual image of a primary instrument cluster at a viewing distance which is greater than the actual optical distance between the dashboard and the driver's eyes in order to enhance instrument readability, minimize driver eye strain, and reduce eye focus problems which are associated with transitioning between the far range viewing used for watching the road ahead and the near range viewing used for glancing at the instruments. A non-pupil forming display system uses a single off-axis aspherical mirror with power to create a virtual image of a miniaturized, multi-color passive image source, such as a segmented LCD panel, which is backlighted by a small filament incandescent light bulb. The aspheric surface is optimized to minimize aberrations and reduce vertical disparity and field curvature. The image source is pre-distorted to compensate for distortion in the off-axis configuration. A holographic diffusing screen element laminated onto the image source provides uniform high brightness and uniform contrast over the entire field-of-view which is visible from an eyellipse sufficient to accomodate most of the driver population, minimizes the visual impact of any optical aberrations near the edge of the viewing area, and provides the non-pupil forming system with some of the desirable optical properties of a pupil forming system.

摘要： A helicopter sight system including an illuminated reticle for controllably providing reticle imaging illumination and an active display for controllably providing active display illumination that contains alignment information provided by an electronic aiming system, the active display and the reticle being controlled to provide respective imaging illumination at different times. The reticle illumination and the active display illumination are directed by a color beam combiner along a common axis to a focussing lens system which illuminates a transparent combiner to produce a reticle image and an active display image viewable by the operator of the helicopter. The focussing lens system, the reticle, and the active display are configured so that the reticle image is positioned at optical infinity and the active display image is positioned at less than optical infinity, whereby the reticle image is positioned at a relatively long optical distance so that the focus of the reticle image sufficiently matches the relatively long distance to the target, and whereby the eyebox for viewing the active display image is larger than the eyebox for viewing the reticle image. More particularly, the reticle is positioned at a distance from the focussing lens system that is equal to the focal length of the focussing lens, and the active display is positioned at a distance from the focussing lens system that is less than the focal length of the focussing lens.

摘要： A radiused fiber optic faceplate is disclosed, particularly suited for use in optical apparatus comprising a high gain diffusion screen or a direct view CRT. The respective optical axis of the fibers are each substantially oriented so that the refracted information-bearing light passed through each fiber is directed to the exit pupil and ambient light from outside the exit pupil is absorbed in the faceplate. The faceplate therefore substantially increases the contrast enhancement.

摘要： A collimating optical device utilizes a reflective beamsplitter in the form of a linear polarizing beamsplitter to achieve a wide field of view. One form of the wide-angle collimating optical device includes, in order from an image source, a first absorptive linear polarizer; a first quarter-wave plate; an optical doublet including a piano-concave singlet, a plano-convex singlet whose convex surface has the same curvature as the curvature of the concave surface, and a first reflective beamsplitter joining the concave surface of the plano-concave singlet to the convex surface of the plano-convex singlet; a second quarter-wave plate; and a second reflective beamsplitter. One of the reflective beamsplitters is a linear polarizing beamsplitter, most preferably a wire grid polarizer.
