Spectral amplitudes of pulsed THz signal on logarithmic (a) and linear (b) scale with chosen scanning speed, respectively. Step mode data: blue; 1 Hz mode data: red; 10 Hz mode data: black; 50 Hz mode data: green. The inset in Fig. 3(b) shows the dependence of the peak dynamic range (PDR) on the scan rate of THz pulse.
