    Abstract: A temperature sensor for measuring a temperature of a substrate in a thermal processing chamber is described. The chamber includes a reflector forming a reflecting cavity with a substrate when the substrate is positioned in the chamber. The temperature sensor includes a probe having an input end positioned to receive radiation from the reflecting cavity, and a detector optically coupled to an output end of the probe. The radiation entering the probe includes reflected radiation and non-reflected radiation. The detector measures an intensity of a first portion of the radiation entering the probe to generate a first intensity signal and measures an intensity of a second portion of the radiation entering the probe to generate a second intensity signal. The detector is configured so that a ratio of the reflected radiation to the non-reflected radiation is higher in the first portion than the second portion. The two intensity signals are used to calculate the temperature and emissivity of the substrate.

    Abstract: A method for estimating the error statistic for retrieved temperature and emissivity of a surface material includes determining the second order analytical error propagation from a measured radiance that differs from the true radiance by additive gaussian noise, which is independent in each band. The radiance error is translated into a diagonal covariance matrix and an analytical estimate results in a determination of the standard deviation and bias of surface temperature. Further, the method for estimating the error statistic utilizes Monte Carlo simulation from a sufficiently large ensemble of radiance spectra for the retrieved surface temperature and emissivity. Temperature and emissivity of the surface material were retrieved using ISSTES algorithm.

    Abstract: The invention is directed to a method of computing the radiation temperature of a body from the signals of a radiation and an ambient temperature sensor, and further to a radiation thermometer, in particular a clinical radiation thermometer. In the method of the present invention, computation of the temperature is not using the Stefan Boltzmann law, but rather, a polynomial is used, preferably a third-degree polynomial, which is adjusted to the radiation-optical properties of the thermometer in the relevant wavelength range. The reciprocal value of the sensitivity of the radiation sensor is preferably represented as a polynomial as well. In this manner, the computation of a fourth root or divisions which are otherwise customary are avoided, enabling the necessary computations to be also performed, for example, by a 4-bit microprocessor with great speed.

    Abstract: An infrared (IR) thermometer for performing temperature measurement of an object without having contact with the object. The IR thermometer comprises at least one IR sensing element which, upon exposure to IR radiation, produces a response. The IR sensing element comprises a flat thermistor flake supported by a substrate. The IR thermometer further comprises a processing circuit which analyzes the response to predict the steady-state response of the at least one IR sensing element and temperature of the object. In one embodiment, the processing circuit may obtain two or more responses separated by a predetermined period of time to predict temperature of the object. The processing circuit may also associate reference data in its prediction algorithm.

    Abstract: A calibration instrument for calibrating a temperature probe, such as pyrometer, uses a stable light source, such as a light emitting diode, to simulate a blackbody of a known temperature. The light source is located inside a chamber and emits light through an aperture. The calibration instrument may be inserted into a thermal processing chamber, or the temperature probe may be removed from the chamber. An alignment tool aligns the aperture to the input of the temperature probe. The calibration instrument may be integrated with the alignment tool, or it may be removable.
