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.
