摘要： A multi-aperture imaging apparatus comprises at least one image sensor, an array of optical channels arranged alongside one another, wherein each optical channel has an optical unit for imaging at least one sub-region of an object region onto an image sensor region of the image sensor, and a beam deflection device for deflecting a beam path of the optical channels in beam deflection regions of the beam deflection device. The beam deflection device is formed as an array of facets which are arranged along a row extension direction of the array of optical channels. Each optical channel is assigned a facet. Each facet has a beam deflection region. A structure that suppresses extraneous light is arranged between a first beam deflection region of a first facet and a second beam deflection region of a second facet arranged adjacent, said structure being designed to reduce a transfer of extraneous light between the first beam deflection region and the second beam deflection region.
