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.

Method for determining a temperature without contact, and infrared measuring system

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.
