Abstract:
The latest achievements in the area of terahertz spectrometers based on transient effects are presented. The potential to use these spectrometers in various applications demanding the composition analysis of multicomponent gas mixtures simultaneously with a high sensitivity (at the ppb level) and resolving power is considered. The results obtained with the use of transient terahertz spectroscopy for medical diagnostics, security systems, etc. are shown.
Keywords:
terahertz frequency range, high resolution spectroscopy, phase switching of radiation acting on gas, fast frequency sweep, multichannel spectroscopy method, multicomponent gas mixture, exhaled air, biological liquid vapors, medical diagnostics, vapors of high energy substances.
