Abstract
The concentration of photothermal (light-to-heat converters) compounds as a function of depth is determined in solid agar gel phantoms. The system contains an 808nm pump laser, which excites the photothermal compound, and a phase sensitive spectral domain optical coherence tomography system, which detects the changes in the optical pathlength of the sample induced by the temperature increase. The derivation of the model is described, and its parameters are empirically determined. The concentration of photothermal compounds are observed from double layer agar gel phantoms.
