“…The signal of latter can be Fourier-transformed and analyzed in frequency domain similar to LIMM. Recently, we have demonstrated that the real part of the pyroelectric current spectra obtained from thermal pulse measurements by Fourier transform is in good agreement with the LIMM spectra when the influence of the transfer function of the measurement setup is corrected [2]. The use of thermal pulses instead of thermal waves enables a significantly shorter measuring time [3].…”
