Abstract
The review of pulsed Fourier spectroscopy methods including the pioneer works (Ekkers and Flygare etc.), and new trends in development of this approach with the nonstationary gas spectroscopy methods in particularly are presented in this work. In particular, such radiation sources as quantum-cascade lasers (QCLs) in the terahertz (THz) frequency range, which make it possible to implement the method of pulsed Fourier spectroscopy, are considered. The presented approach is promising for the development of non-invasive methods of medical diagnostics based on the metabolic analysis of exhaled air, the composition of biological fluids, including vapors and thermal decomposition products of biological fluids. Some examples of the application of non-stationary spectroscopic methods for the analysis of the composition of multicomponent gas mixtures of biological origin are presented.
