Optical measurements in industry increasingly employ techniques which enable a full characterization of the measured object by a differential measurement. Examples for this are camera based measurements of the spatial distribution of temperature or luminance. Based on the differential measurement integral quantities can be determined which enable traceability to SI units. This requires a characterization of the accuracy of the integral quantity. Due to the high dimensionality of the differential measurements and also due to possible correlations therein this is currently not feasible for measurements in industry. This project aims at the development of appropriate methods which can be routinely applied to characterize integral quantities.
