    Abstract: Methods and apparatus are provided to determine the emissivity, temperature and area of an object. The methods and apparatus are designed such that the emissivity and area of the object may be separately determined as functions dependent upon the temperature of the object derived from a three or more band infrared measurement sensor. As such, the methods and apparatus may only require a regression analysis of the temperature of the object without any regression analysis of the emissivity and area of the object.

    Abstract: Method and apparatus for measuring a distribution of emissivity on a surface of an object body, on the basis of a light emitted from the surface of the object body, wherein a temperature of the object body at each picture element of its image is calculated on the basis of a radiant intensity ratio at each pair of corresponding picture elements of a first image and a second image which are obtained with respective two radiations of respective first and second wavelengths selected from the light emitted from the surface of the object body, to measure a distribution of the temperature on the surface of the object body, and an emissivity value at each picture element of the image of the object body is calculated on the basis of the measured distribution of the temperature, and according to a predetermined relationship between the temperature and the emissivity value.

    Abstract: Apparatus and method for non-contact temperature measurement of a film growing on a substrate which accounts for the change in emissivity due to the change in film thickness. The system employs an adaptively calibrated pyrometer wherein the substrate emittance is continuously computed so that the temperature measurement is accurate regardless of the emittance variation. The new system is easily constructed by adding data processing system software and hardware to conventional pyrometers.

    Abstract: Apparatus for measuring the value of the directional spectral hemispherical reflectance of the surface of a target when not engaging but being spaced from the target employs a hollow elongated member having a longitudinal axis and first and second opposite ends. The area of the first end is relatively large relative to that of the second end. The first end is open. The member has an inner chamber extending between the ends and has an inner surface adapted to reflect light falling within a specified wave band. The member when the apparatus is in use is positioned with the first end adjacent but spaced from a selected portion of the surface of the target. The longitudinal axis is oriented essentially normal to a region on the selected surface which would be engaged by a line coincident with the axis and sufficiently extended outwardly from the first end. A beam of light falling within said band is directed within at least a portion of the chamber along the axis and outward through the first end to impinge upon the selected surface portion. A portion of the beam is reflected after said impingement backward through the first end into the chamber. The reflected light which strikes the inner surface of the chamber is directed backwardly within the chamber toward the second end. An electrical signal derived from at least a portion of the backwardly directed light provides a measurement of said reflectance value.

    Abstract: The present invention teaches a 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: Devices and corresponding methods can be provided to measure temperature and/or emissivity of a target. Emissivity of the target need not be known or assumed, and any temperature difference between a sensor and the target need not be zeroed or minimized. No particular bandpass filter is required. Devices can include one or two sensors viewing the same target as the target views different respective viewed temperatures. The respective viewed temperatures can be sensor temperatures, and a single sensor can be set to each of the respective viewed temperatures at different times. An analyzer can determine the temperature and/or emissivity of the target based on the respective viewed temperatures and on plural net heat fluxes detected by the sensors and corresponding to the respective viewed temperatures.
