The application of subTHz and THz nonstationary spectroscopy methods and devices for non-invasive medical diagnostics

Two variants of realization of terahertz frequency range spectrometers based on effects of free damped polarization and fast frequency sweeping are considered. The results of applications of spectrometers developed for detecting ammonia, acetone and nitric oxide in exhaled air as well as for analysis of wash liquid of parenchymatous organs transplanted – custodiol are presented.
