Spectroscopy: Frequency-domain Terahertz generation system

What is it?
A terahertz system relies on simple continuous-wave (CW) lasers. It uses the swept and delayed laser signal in a self-heterodyning scheme for phase-sensitive detection. Based on this method, the amplitude and phase of the terahertz signal can be recovered with software-based lock-in detection.
