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: 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. The temperature measurement values of the measuring pixels are corrected by a pixel-associated temperature drift component determined with reference to the temperature measurement values of the reference pixels.

Abstract: A method for contactlessly establishing a temperature of a surface includes determining the temperature measurement values of the plurality of measurement pixels. The method further includes correcting the temperature measurement values by using in each case a pixel-associated temperature drift component. The method further includes at least temporarily suppressing an incidence of infrared radiation onto the infrared detector array using the closure mechanism of the infrared measurement system while temperature measurement values are being determined. The method further includes determining the temperature drift components using the temperature measurement values.
