| 英文摘要 | Terahertz time-domain spectroscopy (THz-TDS) is widely used in materials, biomedicine, chemistry, pharmacy, security and other fields. Traditional scanning THz-TDS technologies need to scan point by point by changing the time delay between the probe pulse and the THz pulse so as to reconstruct the time domain signals, only suitable for sample detection in THz radiation source with high repetition rate and high stability. However, in the cases of THz radiation source with low repetition rate, large fluctuation, or in irreversible processes, scanning THz-TDS detection technique is not applicable. In these cases, single-shot THz-TDS techniques are desirable. In principle, single-shot THz-TDS technologies require only one shot probe laser pulse to obtain a complete THz temporal waveform. In this article, the main detection techniques in single-shot THz-TDS are introduced. These techniques utilize the Pocket effect of the electro-optic crystal to retrieve the terahertz signal by measuring a physical quantity change of the probe pulse. According to the different single-shot methods, these techniques may be classified into the spectral-encoding technique, spatial-encoding technique and cross-correlation technique. In spectral-encoding technique, different frequency components of probe pulse are separated in time, and different temporal components are modulated by electric fields at different times of THz pulse. |
