An algorithm for the removal of spurious oscillations from spectra derived from THz time-domain data

We present a simple algorithm for removing or reducing spurious oscillations in the THz spectra which result from secondary reflection peaks in samples or optical elements. The algorithm utilizes the fact that a THz time-domain trace containing secondary peaks can be represented as a convolution of the main peak and two or more delta functions.
