摘要： Disclosed is a technology that corrects astigmatism introduced by crossing beam splitting/combining plates. This technology may be used in the context of video projection systems, whereby the plates may be used for combining and/or splitting beams between two or more light modulating panels. In one embodiment, a system is provided for projecting an optical image, where the system includes a lens configured to receive and focus light rays to project the image. The system also includes a first beam splitting/combining plate that refracts light rays passing therethrough, where the refracting creates pluralities of light rays having corresponding optical paths causing each of the pluralities to be focused on corresponding focal planes by the lens. In addition, the system also includes a second beam splitting/combining plate configured to receive the pluralities of rays from the first beam splitting/combining plate, where the second beam splitting/combining plate is oriented with respect to the first beam splitting/combining plate so as to compensate the corresponding optical paths of the pluralities of rays such that each of the pluralities are focused on substantially the same focal plane by the lens.

摘要： A system (S) for combining multi-spectral images of a scene includes a first detector (18) for transmitting a scene image in a first spectral band. A separate, second detector (22) senses the scene in a second spectral band. The second detector (22) has an image output that is representative of the scene. A transparent display (26) mounted in the output viewing path (30) of the first detector (18) and displays a displayed image in the second spectral band. The image of the transparent display is aligned such that the image (12) of the scene in the second spectral band combines with the image output (10) in the first spectral band. The combined multi-spectral images (54) are conveyed to an output (32) for a user (U).

摘要： An image projection system utilizing a convergent light source and an optical polarizing module. The optical polarizing module includes a wire grid polarizing beam splitter (WG-PBS), reflecting S-polarized light, forming a first beam, and transmitting P-polarized light. A mirror is disposed near the WG-PBS at a predetermined acute angle to reflect light with S-polarization, passing through the WG-PBS again and forming a second beam. A first lens array couples the first and second beams and individually directs the first and second beams to different portions on a second lens array. The second beam with P-polarization is directed to a plurality of half-wave plates and converted into S-polarized light, which can be modulated by a liquid crystal display panel to project an image.

摘要： An object (3) is imaged and, after image processing, an image is displayed on a head-mounted display (10) in front of the eyes of a user of the display. The display (10) is constructed with two display modules (13, 14) for displaying the image, designed to be positioned in front of each eye within a limited section of each eye's field of vision, the display modules being arranged each to show a separate image and being designed to leave the field of view free towards the surroundings at least downwards and to the sides of the user. The display modules (13, 14) are advantageously arranged to show two different images, one in front of each eye, so that the user experiences a stereoscopic image with a perception of depth in a part of his field of vision at a predetermined distance in front of his eyes.
