Abstract
A method for determining the accuracy of reflectance measurements with time-domain spectroscopy (TDS) systems was realized - to our knowledge for the first time - after a goniometric measurement setup was constructively improved. Thus, the reference pulse necessary for the evaluation of reflection measurements can now be determined with known precision. This allows the evaluation of the quality of non-destructive testing (NDT) results obtained by THz-TDS reflection measurements.
