Abstract
A thermoconductive sensor for aligning a laser beam which includes a substrate, a dielectric layer disposed on the substrate to provide electrical insulation, an insulating layer interposed between the dielectric layer and the substrate and a reflective/refractive material embedded in the layer to reflect heat from the layer and to conduct heat through a plurality of fingers. A plurality of serially connected thermocouples communicate with the fingers to provide an output of the changes and the thermoconductivity to then realign the laser beam.
