Terahertz time domain spectrometer คืออะไร
http://personal.sut.ac.th/paramate/files/compcom/compcomm03.pdf WebThe time delay between the probe pulse and the THz field is varied to enable the full reconstruction of the waveform in amplitude and phase of the electromagnetic field. Similarly to other ultrafast optical techniques, e.g. pump-probe spectroscopy, the temporal resolution is given by the duration of the probe laser pulse and not by the bandwidth of the …
