摘要: The thermal quadrupole method for flat and spherical multilayered systems heated up with a modulated laser beam is developed analyzed. obtained results take into account the contribution of properties optical absorption coefficient component semi-transparent layers as well their interface resistance, under fully analytical framework. For opaque layers, they reduced to reported in literature. It shown that wave fields reduce ones proper limit on radius layers. By analyzing features normalized amplitude phase function frequency one- two-layer systems, simple useful formulas determine are derived. proposed approach extends applicability deal internal heat sources, it allows determining field any number way, therefore, would be perform characterization layered by means photothermal techniques.
