Abstract: The terahertz (THz) transmission spectra of nitro-compound layers were studied using a THz source based on an impact ionization avalanche transit-time (IMPATT) diode, as well as a photoconductive antenna. The THz spectra were recorded with a Fourier spectrometer based on a Michelson interferometer. A THz video camera with a microbolometer matrix was used as a THz radiation detector. The possibility of spectral identification of nitro compounds by using a THz source based on an IMPATT diode was experimentally demonstrated due to the presence of intense characteristic absorption bands of these substances in the range of its harmonics (0.58–1.45 THz).
Keywords: THz, spectroscopy, IMPATT, nitro compounds, identification.
