Real-time rapid scanning time-domain high-frequency terahertz radiation registration system

This is the authors' abstract. We don't add key points for this paper.

Terahertz time-domain spectroscopy (THz-TDS) is a useful technology that has a wide range of applications. However, the conventional THz-TDS system is very time-consuming for taking time domain measurements due to the usage of the mechanical stepper. While the existing rapid scan method introduces greater complexity to the system. We developed a rapid scan system for real-time THz acquisition using a rapid shaker as the delay line and utilizing a Michelson interferometer to achieve high-accuracy position tracking of the delay line, which enables real-time time-domain measurement for high-frequency THz electrical fields.
