Abstract: Method for measuring the camouflaging capacity of a smoke. A selected radiation source, such as an IR radiation source, is divided into a predetermined number of IR radiating elements (0-7) having mutually differing radiation temperatures. After the release of smoke between the radiation elements and an IR camera, the number of temperature peaks which cannot be distinguished with respect to the background temperature is employed as a measure of the IR camouflaging capacity of the smoke. When measuring the camouflaging capacity of the smoke over a wide area several groups (21-26) of such IR-radiating elements (28, 29) are distributed over the area.

Abstract: The temperature of a pipe is measured accurately without being disturbed by the noises in the surroundings by sensing, from one pipe end, the radiation energy emitted from the inside of the pipe. For this purpose, a radiometer (3) disposed outside the pipe (1) is directed through one end of the pipe (1) towards its inside. It senses the radiation energy emitted from the inside of the pipe (1). The angle θ between the line of sight (3') and a normal line on the measuring point (2) inside the pipe (1) is so chosen that a line axisymmetrical to the radiometer axis 3' intersects the internal surface of the pipe, the axis of symmetry being the normal line N at the measuring point (2).

Abstract: The present invention concerns an unique laser radiometer capable of accurately measuring the radiation temperature of a radiant surface and independently measuring the surface's emissivity. A narrow-band radiometer is combined with a laser reflectometer to measure concurrently radiance and emissivity of a remote, hot surface. Together, radiance and emissivity yield the true surface temperature of the remote target. A narrow receiver bandwidth is attained by one of two methods; (a) heterodyne detection or (b) optical filtering. A direct measurement of emissivity is used to adjust the value obtained for the thermal radiation signal to substantially enhance the accuracy of the temperature measurement for a given subject surface. The technique provides substantially high detection sensitivity over a very narrow spectral bandwidth.

Abstract: This invention is an IR thermometer design using multiple sensor outputs for correcting errors induced by variable probe placement in a patient's ear canal. One embodiment of the system uses two or more sensors (32, 34) to create varying fields of view of the tympanic membrane IR emissions. These discrete IR readings are then reconciled by onboard signal processing to provide an accurate, repeatable and relatively position independent temperature reading.

Abstract: The invention describes a process and device for measuring temperature and layer thickness during coating by prior art methods in semiconductor manufacturing, plasma, ion and other dry-etching plants and in the production of optical coatings. The current results of layer thickness and temperature measurements may be used in process control. The interference phenomena in thermal substrate radiation on the growing layer continuously cause the emissivity epsilon to change during coating, thus preventing the use of pyrometric temperature measurement, which gives rise to particular problems in multi-layer systems in which the current emissivity depends on the thickness of all the layer, their optical constants, the temperature-dependence of the optical constant and the observation angle and wavelength. The present invention solves these fundamental problems by determining the reflectivity R of the wafer using a reflectometer. According to the law of the conservation of energy, for non-transparent substrates epsilon = 1 - R, and hence the current emissivity of the entire (multi-layer) system can be directly determined with the reflectometer. The temperature is measured by means of a given evaluation rule, while the thickness is found by comparing the reflectometer curve with the theoretical layer thickness dependence.

Abstract: A radiation pyrometer assembly and method for sensing the temperature of an elongate body, such as metal strip, moving longitudinally in the direction of its length includes a spray gun which deposits a narrow stripe (5) of black paint of a uniform emissivity, upon one surface of the strip as it moves towards a temperature sensing station. The sensing station includes a calibration radiation pyrometer (6) arranged to view the black stripe (5) once the temperature of the stripe has reached the temperature of the strip. The accuracy of the apparatus may be improved by the provision of a process control radiation pyrometer (7) directed to the opposite, un-painted surface of the strip (1) the combined readings from the two pyrometers allow the correction of otherwise unpredictable errors in the temperature of the strip.

Abstract: An optical temperature measurement technique that utilizes the decaying luminescent intensity characteristic of a sensor composed of a luminescent material that is excited to luminescence by a light pulse or other periodic or other intermittent source of radiation. The luminescent emissions of a preferred sensor exhibit an approximately exponential decay with time that is the average of a distribution of chemically reproducible crystallites and are repeatable with a high degree of accuracy regardless of excitation level or prior temperature history of the sensor.

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.
