METHOD OF DETERMINATION OF CONCENTRATION OF OXYGEN

摘要

FIELD: methods of determination of concentration of oxygen. ^ SUBSTANCE: proposed method includes optical excitation of dye molecules and quenching triplet states of its molecules by oxygen; excitation of dye is performed by scheme of recording dynamic holographic lattices; signal of diffraction of beam recording the hologram is indicative of concentration of oxygen in surrounding medium. ^ EFFECT: extended functional capabilities due to possibility of performing measurements at greater distances as compared with luminescence methods.
