1. An image detection system of optical channels arranged next to one another, each optical channel having an optical axis in an axial direction and having a microlens with an apex and an aperture diaphragm and at least one detector lying in an image plane, said image detection system comprising the at least one detector of each channel having a diameter which is an order of magnitude smaller than a diameter of the microlens and the detectors of the channels being arranged such that directions of respective optical axes form connection lines between the apexes of the microlenses and centers of the detectors and represent a function of a position of the respective optical channel, at least one diaphragm arrangement with a pitch between its diaphragms, the diaphragm arrangement being arranged between the microlenses and the detectors, the microlenses comprising the aperture diaphragms, the pitch of the diaphragms of the diaphragm arrangement lying between a pitch of the microlenses and a pitch of the detectors so that depending on a position of the optical channels, the diaphragms are arranged differently offset to the microlenses and the detectors and each diaphragm lying on a straight line with the detectors and the microlenses, respectively.
