Abstract

The invent on relates to a multichannel optics image capturing apparatus wherein at least a first channel includes anamorphic mapping optics and the first channel has an at least partial field of view overlap with a second channel. Additionally, the invention relates to a multichannel optics image capturing apparatus including at least a first channel and a second channel, wherein the first channel has an at least partial field of view overlap with the second channel, and the second channel includes a first two-dimensional arrangement of detector pixels and the second channel includes a second two-dimensional arrangement of detector pixels, and the first two-dimensional arrangement is incongruent with respect to the second two-dimensional arrangement. The suggested solution achieves that the resolution of an overall image composed of individual images of the channels is essentially distance-independent with respect to an object to be captured.
