  • Publication number: 20160039122
    Abstract: A device for varyingly irradiating by means of ray shaping is described. Furthermore, a method of manufacturing a structure made of a curable material by means of molding is described. In a first step of the method, a molding tool is arranged above a surface such that the curable material abuts on the surface and a molding surface, facing the surface, of the molding tool in a region between the molding tool and the surface and such that further curable material may continue to flow to the region. In a second step, the curable material is irradiated in the region in a locally varying manner such that the ray experiences ray shaping in an optical channel and such that the curable material cures at different speeds in a laterally varying manner.

  • Patent number: 8945458
    Abstract: A method of producing a structure from curable material by molding includes arranging a molding tool above a surface, so that in a region between the molding tool and the surface, the curable material adjoins the surface and a molding face of the molding tool which faces the surface, and so that additional curable material may continue to flow into the region. The method further includes irradiating the curable material in the region in a locally varying manner, so that the curable material cures at different speeds in a laterally varying manner and that shrinkages occurring during curing of the curable material are compensated for by the additional curable material. The method further includes applying a constant pressure to the additional curable material. Moreover, a second method and an apparatus for producing a structure from curable material by molding and a molding tool for an optical component are described.

  • Patent number: 8717485
    Abstract: An improved ratio between hardware/manufacturing expenditure, on the one hand, and picture quality, on the other hand, when using a multi-channel optical element is achieved in that the samples of the pixels are arranged in accordance with an imaging direction from which the optical element images objects on the respective pixel, or with a lateral imaging position in a focal-depth area that is imaged to the respective pixel by the optical element, and when the distribution, thus arranged, of samples of the pixels is interpolated at intersection points of a regular grid extending over the entire distribution of the samples. In this manner, processing is standardized across the entire picture, so that transition problems between the subareas are avoided.

  • Patent number: 8641936
    Abstract: In a method for manufacturing a structure of curable material, a first structure from a first curable material is molded and cured on a substrate, and a second structure of a second curable material is molded and cured on a first surface of the first structure facing away from the substrate, so that at the first surface of the first structure a boundary surface forms between the first and second structures so that the first structure is not covered by the second structure in a passage area. A solvent is introduced into the passage area to dissolve the first curable material of the first structure so that a cavity forms between the second structure and the first surface of the substrate. After curing, the first curable material is soluble and the second curable material is insoluble for the solvent. An optical component and an optical layer stack are made of curable material.

  • Patent number: 8629930
    Abstract: An optical device for imaging is disclosed having at least one micro lens field with at least two micro lenses and one image sensor with at least two image detector matrices. The at least two image detector matrices each include a plurality of image detectors and there is an allocation between the image detector matrices and the micro lenses, so that each micro lens together with an image detector matrix forms an optical channel. The center points of the image detector matrices are shifted laterally by different distances, with respect to centroids, projected onto the image detector matrices, of the micro lens apertures of the associated optical channels, so that the optical channels have different partially overlapping detection areas and so that an overlapping area of the detection areas of two channels is imaged onto the image detector matrices offset with respect to an image detector raster of the image detector matrices. Further, an image processing device and a method for optical imaging are described.

  • Publication number: 20130057748
    Abstract: A device for optically imaging at least part of an object onto an area of a digital image sensor includes an optical channel, which includes a first imaging lens arranged on a first substrate, a second imaging lens arranged on a second substrate, and a field lens arranged on a third substrate. The first and second imaging lenses are identical and arranged such that a first surface of the first imaging lens is a light entry surface of the optical channel and that a first surface of the second imaging lens is a light exit surface of the optical channel. The field lens is arranged between the first imaging lens and the second imaging lens such that an axis running perpendicularly to the lateral extension of the optical channel and through a lateral center of the field lens forms a symmetry axis of the optical channel.
