Abstract

We present experimental data to validate the precision of our continuous wave (CW) THz spectrometer. Measurement data from this new CW spectrometer are compared with corresponding ones obtained using our Agilent vector network analyzer (VNA). Using these systems, terahertz transmission spectra are compared for wild and farm-raised salmon tissues. It is demonstrated that the CW spectrometer provides accurate measurement data comparable with the Agilent-VDI VNA system, but can be improved by increasing its dynamic range.
