Patent ID: 8480300

Claim:
A device for analyzing a beam profile of a laser beam, the device comprising: a carrier plate; a plurality of first temperature-sensitive measuring elements arranged in a first matrix arrangement on a first side of the carrier plate at a plurality of measuring locations; and a plurality of second temperature-sensitive measuring elements arranged in a second matrix arrangement on a second side of the carrier plate opposite the first side, wherein each one of the first temperature-sensitive measuring elements is arranged directly opposite a corresponding one of the second temperature-sensitive measuring elements, wherein, for each directly opposing pair of temperature-sensitive elements, the first temperature-sensitive measuring element and the corresponding second temperature-sensitive measuring element are thermally and electrically connected to one another by strip conductors extending through the carrier plate, such that the thermal connection establishes an approximately zero temperature difference between the first temperature-sensitive measuring element and the second temperature-sensitive measuring element, and wherein the plurality of first temperature sensitive elements comprises a plurality of first diodes, the plurality of second temperature-sensitive elements comprises a plurality of second diodes, and each second diode being connected in an anti-parallel manner to a corresponding first diode opposing the second diode, such that a cathode of the corresponding first diode is electrically connected to an anode of the second diode, and a cathode of the second diode is electrically connected to an anode of the corresponding first diode.
