Random Error in Intensity Spectrum Measured with THz-TDS - No Relation to the Intensity Fluctuation of Fs-Laser

Abstract:

We explored sources of random errors in intensity spectra measured with THz-TDS. Influences of detection accuracies, optical-delay scanning, atmospheric absorption, and intensity fluctuations of fs-laser on the detected THz pulses are discussed based on the standard deviations of measurement data. Those influences on the THz pulses are considerably small and not a predominant cause of the random error.
