Abstract: A radiation clinical thermometer has a probe with an optical guide and an infrared sensor, a detection signal processing section, a body temperature operating section, and a display unit. A filter correction system for setting a correction value based on the transmission wave length characteristics of a filter is also provided. The body temperature operating section receives infrared data, temperature sensitive data, which takes into account the temperature equilibrium between the optical guide and the infrared sensor, and a correction value from the filter correction section so as to calculate body temperature data.

Abstract: A scanning radiation sensor (10) for individually determining temperature of a plurality of spots (16') along a scan line (16) on a target (12) responds to inputs to a light marking apparatus (21, 29, 40, 21) to determine which of a plurality of samples produced during a scan cycle are to be selected for averaging (54, 54'). Averages are determined for each scan (54, 54') and then averages for each scan are averaged over multiple scans (56). Both spot target samples (Ts) and reference source samples (Rs) are averaged for improved accuracy, with target samples being converted to temperatures (52) before averaging.

Abstract: A thermal imager including a cryogenically cooled detector element array and a scanning element has an optical system with a field of view limited by a field stop (2). A retroreflective region (6) is provided on part of the field stop to act as a temperature reference by allowing the detector array to "look at" itself. A second, different temperature reference (5) is provided on another part of the field stop and the two references are used to equalize and adjust the output characteristics of the elements in the detector array.

Abstract: An improved method and apparatus are disclosed for calibrating the emissivity characteristics of a semiconductor wafer within a processing chamber by supporting a sample wafer on a graphite susceptor within the chamber and by comparing the temperature measured within the susceptor in close proximity to the center of the wafer with the temperature measured by the emission of radiation from the surface of the wafer through the walls of the processing chamber. Temperature measurements subsequently made from the radiation emitted from the surface of similar wafers are corrected with reference to the measurement made of the temperature within the susceptor on the sample wafer.

Abstract: An optical fiber thermometer system utilizing the laws of blackbody radiation includes a sensor responsive to the temperature within a region to be tested for transmitting light energy generated as a function of the temperature according to Planck's equation along an optical transmission line, and a detector responsive to the light energy for producing an electrical current. The current is amplified by a linear amplifier having provision for automatically controlling the gain of the amplifier, depending upon the magnitude of the input current, to reduce the dynamic range of the input current. The output of the linear amplifier is a voltage which is used by a signal processing network to yield an accurate indication of the temperature within the region to be tested by solving the Planck equation between two predetermined wavelengths representing upper and lower limits of an optical filter which filters light energy entering the detector.

Abstract: A hand held probe unit has an infrared sensitive thermopile mounted in a metal housing kept at a constant reference temperature by a regulator circuit. A waveguide tube, surrounded by a thermally insulative probe, directs infrared emissions to the thermopile. The thermopile and regulator circuit of the probe unit are electrically connected to processing circuitry in a chopper unit. Prior to taking a patient's temperature, the probe unit is mated with the chopper unit so that the thermopile detects infrared emissions from a reference target which is also kept at a constant reference temperature by another regulator circuit. The processing circuitry repeatedly acquires the output level of the thermopile and stores calibration data. The probe unit is then removed from the chopper unit, the probe is covered with an IR transparent, disposable speculum, and is inserted in the patient's external ear canal. The processing circuitry then determines the patient's core temperature by comparing the stored calibration data to the maximum output of the thermopile during a succession of ear canal samplings.

Abstract: A method and apparatus for measuring the absorptivity of a radiation detector by making the detector an integral part of a cavity radiometer. By substituting the detector for the surface of the cavity upon which the radiation first impinges a comparison is made between the quantity of radiation incident upon the detector and the quantity reflected from the detector. The difference between the two is a measurement of the amount of radiation absorbed by the detector.
