Problems with interpretation of experimental data from the investigation of a diffusion process using photoacoustic effect are considered. Based on Fick's 2nd law the problem of drug diffu-ption through the membrane is solved, and distribution of drug concentration in membrane as a function of time is calculated. The obtained solution allows one to derive the distribution of heat sources arising in the membrane illuminated by intensity modulated light. Subsequently the temperature of the illuminated membrane surface is analyzed numerically. Results of theoretical analysis are compared qualitatively with experimental data.
