Using the effective medium model, the complex permittivity of the ocular surface system in the THz frequency range is considered. The penetration depth of THz radiation and the sensitivity of the ...reflected component to the dynamics of evaporation of the tear film are discussed. The results of in vivo experiments aimed to determine the reflection coefficient of the ocular surface using continuous THz reflectometers are well described using the developed model.
Terahertz frequency-domain reflectometry is applied for sensing of human corneal tissue hydration level and dynamical control of the tear film in clinical applications.
Scintillation properties of (Zn0.9Pb0.1)(W0.9Mo0.1)O4 and (Zn0.9Cd0.1)(W0.9Mo0.1)O4 mixed crystals with doping of Eu, Sm, Pr, Ce, Sc, Yt and Nb are studied. Measurements of their light yields ...relative to pure ZnWO4} at room temperature, decay times and energy resolutions at 662 keV are presented. Emission spectra are obtained with 239Pu source of alpha particles.
