Lock-in Detection of Terahertz Spectra Captured by Plasmonic Heterodyne Terahertz Spectrometers
We present a lock-in detection technique that enhances the signal-to-noise ratio of captured spectra in plasmonic heterodyne terahertz spectrometers, achieving a noise reduction rate of 10 dB per decade of integration time while preserving spectral information.
