We can determine many properties of objects by measuring the optical radiation which will be reflected or emitted by these objects. Intensity and polarisation of the radiation and its spectral, spatial and temporal distribution carry the desired information. The measuring instruments produce digital data which combine the properties of the radiation and the properties of the instrument.
The calibration procedure delivers the parameter of an instrument in physical units. These parameter, for example wavelengtgh, FOV or response, effect the measured data and they are needed to deduce the properties of the object under investigation.
The calibration of an instrument is the basis for a scientific interpretation of the data and for the comparability of the results.
We in our department use and offer the following spectral-optical and radiometrical calibration equipment:
Instruments for measuring of spectral data:
The camera-calibration-facility of the Department OS can be used for geometric, radiometric and spectral calibration of optoelectronical systems.
The following calibration.measurements can be done with high performance and precision:
