In this work we provide a full review of the absolute calibration of ECE quasi-optical diagnostics, such as Fourier transform spectrometers. The optimisation of the overall process of averaging the interferograms to extract a reliable calibration curve are discussed. The basic assumptions, for example the linearity of the detector and the achievability of a given signal to noise ratio, are pointed out. Finally the actual physical meaning and the "accuracy versus precision" characteristics of the calibration curve are analysed.

Abstract
In this work we provide a full review of the absolute calibration of ECE quasi-optical diagnostics, such as Fourier transform spectrometers. The optimisation of the overall process of averaging the interferograms to extract a reliable calibration curve are discussed. The basic assumptions, for example the linearity of the detector and the achievability of a given signal to noise ratio, are pointed out. Finally the actual physical meaning and the "accuracy versus precision" characteristics of the calibration curve are analysed.File in questo prodotto:
