The present invention pertains to a device for measuring a temperature distribution, which can measure a temperature distribution without contacting a minor sample having a three-dimensional structure. More particularly, the device for measuring the temperature distribution can measure a three-dimensional temperature distribution for a sample, wherein the temperature distribution in a depth direction (direction z) of the sample is measured by a thermo-reflectance technique using a chromatic dispersion lens, a diffraction spectrometer and an optical detection array; and the temperature distribution in parallel directions (direction x-y axes) of the sample is measured by the thermo-reflectance technique using a biaxial scanning mirror.

The present disclosure discusses various systems and methods for screening individuals for an elevated skin temperature, including substantially reducing the footprint of conventional thermal imaging system. The footprint of the currently available thermal imaging system is reduced in part because rather than having a blackbody and a person being screened simultaneously located within the thermal camera's field of view, the present disclosure discusses a unique thermal imaging system that provides a reference temperature to the system for subsequent comparison to the thermal camera, using a blackbody, prior to the thermal scanning and imaging the person.

A method and apparatus for calibration non-contact temperature sensors within a process chamber are described herein. The calibration of the non-contact temperature sensors includes the utilization of a band edge detector to determine the band edge absorption wavelength of a substrate. The band edge detector is configured to measure the intensity of a range of wavelengths and determines the actual temperature of a substrate based off the band edge absorption wavelength and the material of the substrate. The calibration method is automated and does not require human intervention or disassembly of a process chamber for each calibration.
