20110134040 | OPTICAL NAVIGATION DEVICE - A device for optical navigation, containing an image sensor which has a large number of image sensor units which are disposed in an array-like manner with respectively at least one light-sensitive surface and at least one lens which is disposed between an object to be imaged and the image sensor. A microlens array is present, at least one microlens being assigned to one image sensor unit. | 06-09-2011 |
20110228142 | DEVICE, IMAGE PROCESSING DEVICE AND METHOD FOR OPTICAL IMAGING - 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. | 09-22-2011 |
20120081801 | LENS AND METHOD FOR MANUFACTURING SAME - In a method for manufacturing a lens, a substrate is provided which includes recess in a first surface thereof. A lens structure having a first desired lens surface and a second desired lens surface is formed in the substrate's recess. | 04-05-2012 |
20120175796 | Method and Apparatus for Producing a Structure, Molding Tool - 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. | 07-12-2012 |
20120182623 | Method for Manufacturing a Structure, Optical Component, Optical Layer Stack - 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. | 07-19-2012 |
20120200946 | OPTICAL LAYER STACK AND METHOD FOR MANUFACTURING THE SAME - An optical layer stack having a first layer, a second layer, a first spacer part associated with the first layer and a second spacer part associated with the second layer, wherein the two spacer parts have groove and tongue for an engagement in a stacking direction of the optical layer stack in order to provide a connection between the first and the second spacer part and a spacing of the first and the second layer in stacking direction. | 08-09-2012 |
20130250432 | METHOD FOR MANUFACTURING A STRUCTURE, OPTICAL COMPONENT, OPTICAL LAYER STACK - 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. | 09-26-2013 |
20140253451 | OPTICAL NAVIGATION DEVICE - A device for optical navigation, containing an image sensor which has a large number of image sensor units which are disposed in an array-like manner with respectively at least one light-sensitive surface and at least one lens which is disposed between an object to be imaged and the image sensor.
