Abstract :
Terahertz time domain spectroscopy (THz-TDS) currently requires expensive components, in particular an ultra-fast Ti:Sapphire laser, and signal acquisition is not a real time process. In order to speed up the process for acquiring sample and reference data, we propose to approach dual scanning THz-TDS by using a single fast high precision translation stage and a single lock-in amplifier.
