摘要：

A mathematical model of damped harmonic oscillators based on the Lorentz equations for calculating the optical characteristics of a medium is considered. Using an experimental setup built on the basis of an infrared quantum-cascade laser in the wavelength range of 5.3-12.8 mu m with a peak power of up to 150 mW, diffuse scattering spectra of individual potassium perchlorate crystals are recorded. The transmission spectra are calculated using the Kramers-Kronig relations and the recorded scattering spectra. The model parameters are obtained based on the Lorentz equations for the scattering spectra of potassium perchlorate, which makes it possible to calculate the transmission spectra. The latter can be used to detect substances, including those in trace amounts, on various surfaces.
