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.

One example temperature sensing device includes an electronic processor configured to receive a thermal image of a person captured by a thermal camera. The electronic processor is configured to determine a first temperature and a first location of a first hotspot on the person. The electronic processor is configured to determine a second location of a second hotspot on the person based on the second location being approximately symmetrical with respect to the first location about an axis, and the second hotspot having a second temperature that is approximately equal to the first temperature. The electronic processor is configured to determine a distance between the first location of the first hotspot and the second location of the second hotspot. In response to determining that the distance is within the predetermined range of distances, the electronic processor is configured to generate and output an estimated temperature of the person.

Provided is a method of calibrating a microwave radiometer, which eliminates use of liquid nitrogen as a calibration source. The method is applied to a microwave radiometer configured to receive, by a receiver having a primary radiator connected thereto, a radio wave emitted from an object to be measured depending on a temperature of the object to be measured and to measure a brightness temperature of the object to be measured from an output signal of the receiver. In the method, the method a noise temperature T.sub.rx of the receiver appearing on an output side of the receiver is calibrated by observing a plurality of calibration sources having known brightness temperatures. The method includes using a radio wave reflector configured to totally reflect noise radiated from an input side of the receiver as one of the plurality of calibration sources.
