Abstract

According to the invention, the image detection system contains optical channels arranged one next to the other with a respectively assigned microlens with aperture and in each case at least one detector located in the image plane, wherein the detectors are arranged such that the directions of the optical axes, which form in each case the connecting lines between lens apices and centre of the detectors, represent a function of the position of the respective optical channel, wherein at least one aperture stop arrangement (4) is provided between the microlenses (1′) with aperture (2′) and the detectors (6′, 8), wherein the distance between centres of the aperture stops (4′) is located between the distance between apices of the microlenses (1′) and distance between centres of the detectors (6′, 8) such that, depending on the position of the channels, the aperture stops (4′) are arranged with different offsets to the microlenses (1′) and the detectors (6′, 8) and are in each case located on a straight line with them.
