Abstract:
A thermoelectric infrared detector. The detector includes an absorption platform comprising a material that increases in temperature in response to incident infrared radiation, the platform covering substantially an entire area of the detector. The detector includes a thermocouple substantially suspended from contact with a substrate by at least one arm connected to the substrate and a thermal connection between the absorption platform and the thermocouple.
Abstract:
The isothermal radiometric system improved is of the double junction variety (preferably copper-constantan-copper) and includes a black body housing (B1) defining a central concavity. The central concavity has a black body disk (D1) at the bottom thereof. The disk is preferably suspended by a copper (14) and a constantan (16) wire with one junction (32) formed on the surface of the disk and the other junction (34) formed on the surface of the housing. The improvement includes a plurality of and preferably three annular baffles (50, 52, 54) defining central, circular and preferably concentric opening. These baffles are lodged in the opening (30) of the housing above the mounted radiometer disk (D1). The annular baffles on the side towards the radiation source are coated as a black body so as to increase the thermal coupling of the black body housing to the ambient being radiometrically observed. The baffles on the side away from the radiation source and exposed to the radiometer disk are reflectively coated to decrease further any couple between the radiometer disk and the black body housing. The combination of the baffles and the disk combine to give the radiometer a small field of view which permits radiometric thermal measurement of a small solid angle and ignores the remainder of the environment. Preferred use of the radiometer in looking at a centrifuge rotor (R1) is disclosed.
