Abstract :
We have observed that random errors in THz intensity spectra which are much larger than the noise floor. The standard deviation in intensity and phase spectra measured with THz-TDS are almost proportional to THz intensity and phase respectively and common for reference and sample. We discuss on the characteristics related to the origin of the random errors.
