Abstract:
1. A detection device comprising a parabolic mirror and several radiation detectors placed in a focal plane of said mirror, said focal plane being substantially perpendicular to an axis of the mirror and containing a focus of the mirror, the detectors being positioned with respective offsets along a determined common direction parallel to the focal plane of the mirror, the detection device furthermore comprising a selection system connected to each of the detectors and devised so as to successively select just one ofthe detectors and to transmit a reception signal originating from the selected detector, the respective offsets of the detectors in the focal plane of the mirror being chosen so that a reception gain diagram of said device exhibits, between two successive gain maxima in said diagram and corresponding respectively to one of the detectors, a gain minimum of less than 3.0 dB below each of said gain maxima.
