1. Photoconductor-based electromagnetic wave detector including:

  • at least one first and one second overlaid plane active detector elements separated by a common layer, said first and second detector elements being sensitive to the different wavelengths;

    a first means of connection connected in common to said first and second detector elements, a second means of connection connected to said first detector element, and a third means of connection connected to said second detector element;

    means for applying control voltages successively to each means of connection;

    means connected to said first means of connection to detect a photoconduction current each time a control voltage is applied, wherein said common layer is an insulating layer, said first means of connection is connected to a first end of each detector element, and said second and third means of connection are each connected to a second end of a detector element, said first and second ends of each detector element being opposite ends of the detector element.
