摘要： Disclosed is an illumination system using optical feedback to maintain a predetermined illumination output. The illumination system employs an electrically controllable optical filter (106) for filtering light incident thereon and a light detector (304). The light detector is in data communication with the electrically controllable optical filter. Some or all light filtered by the electrically controllable optical filter is detected by the light detector and compared to at least one predeterminated value. If the signal generated by the light detector differs when compared to the at least one predeterminated value, one or more filtering characteristics of electrically controllable optical filter are varied which, in turn, varies the amount of light filtered by the electrically controllable optical filter. The filtering characteristics of the electrically controllable optical filter continue to be varied until the signal generated by the light detector substantially matches the at least one predeterminated value.

摘要： A projection system (26; 60; 80; 88; 102; 122) and a method of displaying a projected input image on a projection screen (14; 30; 96; 104; 124) of the system utilize one or more reconfigurable holographic optical elements (HOEs) (42, 44, 46, 54, 56 and 58; 64, 66, 68 and 70; 98; 106 and 108; 126 and 128) to optically manipulate propagating light in the system. The reconfigurable HOEs may be configured to perform simple optical functions that are commonly associated with traditional optical devices, such as lenses, prisms and mirrors. However, the reconfigurable HOEs may also be configured to perform sophisticated optical manipulations, such as varying the light intensity toward a specific direction and generating virtual (holographic) images. Each reconfigurable HOE includes a hologram that is sandwiched between two electrode layers. The hologram is a holographic photopolymeric film that has been combined with liquid crystal. The hologram has an optical property that changes in response to an applied electrical field. The reconfigurable HOEs may be included in a color filter (38) of the system to selectively diffract tristimulus color lights to a display panel (40) in order to provide a color display of the input image that is projected onto the projection screen. The reconfigurable HOEs may also be included in a projection optics (34; 62) to magnify the projected image on the projection screen and/or redirect the projected image to form a tiled image on the projection screen. Furthermore, the reconfigurable HOEs may be used in the projection screen to vary the light intensity toward specific viewing positions. In one application, the reconfigurable HOEs in the projection screen allow the system to present the display image in a stereoscopic form.

摘要： The present invention relates to an optical condenser as well as to optical devices comprising this condenser which can be used in projection systems, in display screens, in information panels or other devices. The condenser and optical devices include a concentrator-lens raster for concentrating light which is made in the shape of a matrix comprising a plurality of hollow concentrators as well as a lens raster. Each concentrator is made in the shape of a truncated cone or pyramid comprising a lateral envelope, an input-end reflector and a transparent output end for reflecting light inside said concentrator. The light-collecting lenses of the raster are either tightly attached to the concentrator output ends and made in the shape of a monolithic lens raster, or fixed to the lens raster and associated with the output ends. This lens raster can be realised from spherical lenses made of glass. In the case of optical devices comprising a concentrator-lens raster at the input ends, light sources are arranged inside said concentrators while additional light sources and/or reflectors and/or anti-flare coatings are applied outside said concentrators and/or on the rear side of the lens raster. Photo-conductors can also be placed at the concentrator input ends and/or between the concentrators and the lens raster, wherein said photo-conductors are used for introducing into the concentrator light rays which are provided by external illumination from outer light sources arranged behind the condenser ends. The input-end reflectors, the concentrator side surfaces and the lens raster can be made transparent for the light exciting the luminophores.

摘要： A projection system is described for projecting a mask pattern on a substrate by means of EUV radiation, which projection system consecutively comprises a first concave mirror (1), a convex mirror (2) and a second concave mirror (3). Since the system has a focal length f which is at least equal to +1/2 L, in which L is the length of the system, and the chief ray of the object beam (b) leaving the object plane (V) is inclined towards the optical axis (OO'), a compact system is obtained whose first concave mirror (1) has relatively moderate dimensions and in which the axial positions of the concave mirrors (1, 3) are approximately equal, so that these mirrors can be arranged on a common support.

摘要： An optical system includes a light-guide optical element (LOE) (10) having mutually-parallel first and second major external surfaces (11, 12) for guiding light by internal reflection, and a projector (100) that projects illumination corresponding to a collimated image from an aperture (101). The projector injects light in to the LOE via a coupling prism (30) attached to the first major external surface (11) that projects an image injection surface. A reflective polarizing beam splitter (51) is deployed at an interface between the major external surface (11) and the coupling prism (30) parallel to the major external surfaces, to selectively transmit illumination from the coupling prism into the LOE while trapping light already within the LOE so as to propagate within the LOE by internal reflection.
