摘要： Devices and methods for measurement of energy from a defined source having increased accuracy in measuring low energies. The device comprises a housing containing sensors. A first sensor receives energy from the source and produces a first output. A second sensor receives ambient energy only and produces a second output. Subtraction of the second output from the first output produces a more accurate corrected output. The method includes providing a housing containing a first sensor and a second sensor and directing energy from the defined source to a surface of the first sensor thereby causing the first sensor to produce a first output while only ambient energy from sources other than the defined source is applied to a surface of the second sensor which produce a second output that is subtracted from the first output producing a corrected output.

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 technique for performing background suppression in photodiode detectors is disclosed. A first detector measures the light emitted by the source to be measured and the background light, while a second detector simultaneously measures the background light only. The value measured by the second detector is subtracted from the value measured by the first detector, and the difference represents the portion of the first detector's measured value which is attributable to the source to be measured.
