Abstract
Device for the detection of optical parameters consisting of a first sensing element that is sectioned into a plurality of equal regions each able to produce an electric signal, proportional to the power of the incident laser beam. Before said first sensing element with respect to the direction of the incident laser beam, at least a second sensing element is provided, lined up with the first sensing element and thermally insulated from it, that has a hole with a shape equal to the shape of the incoming laser beam and with dimensions increasing with the distance from that first element.
