  • Patent number: 8777424
    Abstract: A projection display having at least one light source and also regularly-disposed optical channels. The optical channels comprise at least one field lens, to which respectively one object structure to be imaged and also at least one projection lens are assigned. The distance of the projection lenses from the assigned object structures corresponds to the focal distance of the projection lenses while the distance of the object structures to be imaged from the assigned field lens is chosen such that a Köhler illumination of the assigned projection lens is made possible. Then the individual projections are superimposed to form the total image.

  • Publication number: 20140146290
    Abstract: A projection display with an imaging system is described, which is implemented to generate individual images in a distribution, such as a two-dimensional distribution, of sub-areas of an imaging plane of the imaging system, and a multi-channel optics that is configured to map one allocated individual image or one allocated sub-area of the imaging system each per channel, such that the mapping of the individual images is at least partly superimposed to an overall image in a projection surface, wherein the projection surface is a non-planar free-form surface, such as a curved surface, and/or tilted with respect to the imaging plane, and the imaging system is implemented such that constellations of points in the sub-images, each superimposed in a respective common point in the overall image by the multi-channel optics, differ depending on what distance the respective common point in the overall image has to the multi-channel optics.

  • Publication number: 20110304825
    Abstract: A projection display includes at least one light source, at least one reflective image generator configured to represent frames in a two-dimensional distribution of subareas of same, a projection optics arrangement having a two-dimensional arrangement of optical projection elements and being configured to image an associated subarea of the at least one image generator onto an image plane in each case, so that images of the frames superimpose within the image plane to form an overall picture, and at least one beam splitter arranged within an optical path between the at least one reflective image generator and the two-dimensional arrangement of optical projection elements, on the one hand, and the optical path between the at least one light source and the at least one reflective image generator, on the other hand.
