A home-built scattering-type scanning near-field millimeter-wave microscope based on a 110-GHz continuous-wave solid-state source is demonstrated with a spatial resolution of 1 μm, approximately 1/3000 of the incident wavelength, and a signal-to-noi

In terahertz time-domain spectroscopy (THz-TDS), the THz electric field strength is generally characterized by the photocurrent of the THz receiver, which is extracted from the in-phase component output of lock-in amplifier (LIA) in the system. As to

The 8th International Symposium on Ultrafast Phenomena and Terahertz Waves.
To improve the low resolution of differential frequency signal processing associated with CW THz nondestructive testing, we proposed a novel IF signal processing scheme, with a significantly improved resolution, without sacrifice in dynamic range.
