Abstract

Multi-aperture imaging device includes at least one image sensor, an array of juxtaposed optical channels, wherein each optical channel has optics for projecting at least one partial area of an object area on an image sensor area of the image sensor, and a beam deflector for deflecting an optical path of the optical channels in beam-deflecting areas of the beam deflector. The beam deflector is formed as an array of facets arranged along a line-extension direction of the array of optical channels. One facet is allocated to each optical channel. Each facet has a beam-deflecting area. A stray light suppressing structure is arranged between a first beam-deflecting area of a first facet and a second beam-deflecting area of a juxtaposed second facet, which is configured to reduce transition of stray light between the first beam-deflecting area and the second beam-deflecting area.
