Patent number: 9826204Abstract: Generating images to be projected at different projection distances with a multi-aperture projection display, statically or without any conversion, neither mechanically nor at the imager, is enabled by designing the single images of the multi-aperture projection display in a suitable manner, namely by combining provisional single images for the projection channels of the multi-aperture projection display, which are intended for each of the at least two images to be projected, projection channel by projection channel, to the actual or final single images.Type: GrantFiled: November 10, 2015Date of Patent: November 21, 2017Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Marcel Sieler, Peter Schreiber, Alf Riedel

Patent number: 9800850Abstract: A projection display is provided with an imager that is implemented to generate individual images in a distribution of sub-areas of an imaging plane of the imager. The projection display also includes a multi-channel optics, which is configured to map one allocated sub-area of the imager each per channel, such that the mappings of the individual images are combined to an overall image in a projection area. At least some channels of the multi-channel optics are arranged along at least one curve which is similar to at least one elongated image feature of the overall image, so that a two-dimension anisotropic out-of-focus behavior of each projected image point is obtained. In this way, a large depth of focus range can be combined with relatively high projection brightness without having to accept losses with respect to the focused illustration of image features that are to be projected with sufficient focus.Type: GrantFiled: November 7, 2014Date of Patent: October 24, 2017Assignee: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Peter Schreiber, Marcel Sieler

Patent number: 9746673Abstract: A projection display includes an imager for displaying sub-images in a two-dimensional distribution of sub-areas of the imager and a projection optics array with a two-dimensional distribution of projection optics. The projection optics array is configured to superimpose projections of the sub-images to an overall image in an image plane such that a mutual area overlap of the projections of the sub-images in the image plane in pairs results, which is between 0.1 and 0.8 for all pairs. Here, the projection display is implemented such that the overall image is a virtual overall image.Type: GrantFiled: September 29, 2014Date of Patent: August 29, 2017Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Peter Schreiber, Marcel Sieler, Matthias Kraus
