Abstract :
We present the analysis of different schemes for simultaneous acquisition of an electric signal. The results can be used to monitor-based source-drift correction for optical metrology. The degree of correlation between the measured signals is expected to directly influence on the calibration uncertainty in applications in Radiometry.
