Abstract

We report photothermal measurements made on turbid tissue phantoms using an optical fibre sensor that we are developing for biomedical diagnostics. The ability of the sensor to detect changes in optical properties in the physiological range is demonstrated. The absorption coefficients of nonscattering liquid absorbers were determined, in a more simple geometry, using an isolated polymer film Fabry-Perot interferometer and a one-dimensional analytical theory of heat transport.
