Abstract: A method and an infrared measuring system for determining a temperature distribution of a surface without contact includes an infrared detector array with a detector array substrate and respective pluralities of measuring pixels and reference pixels. The measuring pixels are each connected to the detector array substrate with a first thermal conductivity, are sensitive to infrared radiation, and each provide a measurement signal for determining a temperature measurement value that depends on the intensity of the incident infrared radiation. The reference pixels are each connected to the detector array substrate with a second thermal conductivity and each provide a measurement signal for determining a temperature measurement value. The reference pixels are implemented as blind pixels that are substantially insensitive to infrared radiation.

Abstract: A method for contactlessly establishing a temperature of a surface includes determining the temperature measurement values of the plurality of blind pixels and determining temperature measurement values of the plurality of measurement pixels. The method further includes determining a temperature measurement value and a temperature measurement values by subtracting the temperature measurement value of the first blind pixel of the plurality of blind pixels from a temperature measurement value of a second blind pixel of the plurality of blind. The method further includes correcting the temperature measurement values by pixel-associated temperature drift components in each case, wherein the temperature drift components are determined using the temperature measurement value and/or the temperature measurement value.

Abstract: An apparatus is configured to detect skin cancer using THz radiation. A high frequency source generates a high-frequency signal. A power splitter divides the high-frequency signal between a transmission branch and a reception branch. A first frequency multiplier multiplies the frequency of the high-frequency signal. A transmission antenna emits the multiplied high-frequency signal as THz radiation. A frequency generator generates a low-frequency signal. A mixer mixes the high-frequency and low-frequency signals to generate a mixed-frequency signal. A second frequency multiplier multiplies the mixed-frequency signal. A reception antenna device receives the THz radiation and generates a THz signal. The mixing device mixes the THz signal with multiplied mixed-frequency signal to generate a measurement signal. The evaluation device evaluates the measurement signal.
