ABSTRACT:
A detector of pulses of electromagnetic radiation, especially of laser pulses, comprising as sensor at least one cylindrical body of material translucent to the electromagnetic radiation having a capture window on its surface of revolution. The cylindrical body is provided with an internal metallization delimiting the cylindrical body in two parts subject to selective photodetection, to obtain a sensitivity in bearing and/or in elevation. The body is extended at one end by a non-diffusing transparent part, likewise traversed by the internal metallization. The extension is externally metallized and serves for the link with photodetectors.
