摘要： A power measuring sensor for an optical beam which utilizes the temperature difference across a thin layer of heat insulating material, generated by the axial flow of the absorbed beam, from an absorber layer on which the beam impinges, to a cooled heat sink which dissipates the heat after passage through the sensor. The axial heat flow is measured by means of a continuous matrix of adjacent thermocouple junctions over the heat flow region of the sensor disc, with the thermal insulating layer, which generates the temperature drop, having thicker and thinner regions at alternate junctions. The junctions on the thicker regions of the insulator thus become the hot junctions, and those on the thinner regions of the insulating layer become the cold junctions, and the sum of the voltages generated by the thermocouples is proportional to the flow of heat, and thus to the incident optical power.

摘要： A laser power meter incorporating an absorber disc with a peripheral thermopile ring, either continuous or segmented, and an additional temperature detection element in the central portion, that enables measurement of beam size. This detection element can be a thermopile element, generally a ring of smaller diameter than the peripheral thermopile used, and located closer to the center of the absorber disc. With this arrangement the beam size can be measured, in addition to measurements of the power and the position of the beam. Alternatively, this centralized detection element can be a single thermocouple junction located at the center of the disc, which acts as the hot junction of a thermocouple pair. The second or cold junction is effectively located on the disc close to the peripheral thermopile. Alternatively, two temperature measuring elements can be used, one at the disc center and one at the periphery.
