    Abstract: In order to derive the temperature in the mesopause region from hydroxyl (OH*) airglow, in which intensities of three lines of OH* emission and a basic position are measured during the night using ground-based IR spectrometers, a noisy OH* spectrum is smoothed by filtering out white noise superimposed on the measured OH* intensities, by means of a spectral analysis method in the form of a harmonic analysis and by means of adaptation using the Voigt function which is carried out in the form of a combination of a Lorentz distribution and a Doppler distribution. A decision is made on the quality of the adaptation of the smoothed spectrum obtained to the original spectrum using statistical characteristic variables and by selecting one of the two methods, harmonic analysis function or Voigt function, and the temperature is thus accurately determined.

  • Publication number: 20090296774
    Abstract: Embodiments of the invention provide a method and an apparatus for detecting the temperature of a substrate surface. In one embodiment, a method for measuring the temperature is provided which includes exposing the surface of the substrate to a laser beam radiating from a laser source, radiating emitted light from a portion of the surface of the substrate, through the shadow ring, and towards a thermal sensor, and determining the temperature of the portion of the surface of the substrate from the emitted light. The substrate may be disposed on a substrate support within a treatment region and a shadow ring may be disposed between the laser source and the surface of the substrate. The shadow ring may be selectively opaque to the laser beam and transparent to the emitted light.

  • Publication number: 20090296775
    Abstract: An ear thermometer which includes a temperature detection element and infrared detection element arranged near the opening portion of a probe achieves a reduction in manufacturing cost while reducing the influence of thermal shock. This invention provides an ear thermometer incorporating, in a probe, a temperature detection element to detect an environmental temperature and an infrared detection element to detect infrared radiation emitted from a temperature measurement region in an earhole. The probe includes an end face portion having an opening in its distal end, an inner surface portion of a hollow cylindrical member, and an inwardly protruding engaging portion. A detection element housing is fixed to close the opening of the probe and to form an air layer between the detection element housing and the probe.

  • Patent number: 7616872
    Abstract: Temperature measurement and heat-treating methods and systems. One method includes identifying a temperature of a first surface of a workpiece, and controlling energy of an irradiance flash incident on the first surface of the workpiece, in response to the temperature of the first surface. Identifying may include identifying the temperature of the first surface during an initial portion of the irradiance flash, and controlling may include controlling the power of a remaining portion of the irradiance flash. The first surface of the workpiece may include a device side of a semiconductor wafer.

  • Patent number: 7611278
    Abstract: The present invention is directed to a hand-held infrared thermometer or radiometer (1) for measuring, remotely, the temperature of a target surface (3). In one embodiment, the radiometer includes an infrared detector (7), associated optical system (7), and associated circuitry and an LCD display (21). Built into or mounted on the radiometer is a distance measuring device (2), the operation of which is controlled by the radiometer. The device (2) includes an ultrasonic transmitter/receiver (12) and associated circuitry for calculating, from a comparison of the transmitted and received pulses, the distance of the radiometer from the target surface. The distance-to-target is displayed on the LCD display (21).

  • Patent number: 7611277
    Abstract: Egg candling methods and apparatus are provided wherein non-live eggs, inverted egg, and side air cell eggs can be quickly identified. A method of candling eggs includes exposing a plurality of incubated eggs to an environment having a temperature different from a temperature at which the eggs were incubated; obtaining a thermal image of the eggs; and analyzing the thermal image to obtain surface temperature information for each egg. The surface temperature information is utilized to designate each egg as live/non-live, inverted, or having a side air cell.

  • Patent number: 7607825
    Abstract: Method and apparatus for monitoring formation of deposits of solid particles from flue gas onto furnace walls formed of welded-together tubes through which cooling medium flows. For the entire surface of the walls, the exact surface temperature is detected with infrared cameras, offset by 90° relative to one another, via a thermal image obtained of a surface development of the furnace. This exact surface temperature is compared with the temperature of the cooling medium from measurement locations. Individual images from the cameras are composed to form an overall development of the inner surface of the furnace walls. The coordinates of the deposits on the walls are determined from the overall development, and the thickness of the deposits is determined from the temperature comparison.

  • Publication number: 20090262778
    Abstract: An electronic device according to the present invention includes an infrared ray absorbing section 12, which comes to have an increased temperature when irradiated with an incident infrared ray, and at least one heat sensing section 13, of which a physical property varies with the variation in temperature that has been caused due to the heat generated by the infrared ray absorbing section 12. The relative positions of the heat sensing section 13 and the infrared ray absorbing section 12 can be changed so as to switch their states from a first state, in which the infrared ray absorbing section 12 and the heat sensing section 13 are in contact with each other, into a second state, in which the infrared ray absorbing section 12 and the heat sensing section 13 are out of contact with each other, and vice versa.

    Abstract: This invention relates to optical sighting apparatus systems, and to methods for visualization and for identifying remote target surface areas without physical contact for the purpose of measurement and/or of treatment of the remote surface. An arrangement of projected light beams indicates the position and size of the target surface in relation to a measurement detector or treatment device, so that the device is accurately directed to the target. In a preferred arrangement separate laser beams form a light distribution indication or brightness pattern at the target and the device is sighted toward the pattern on the target surface area.
