Abstract

Frequency-domain IR photothermal radiometry is introduced as a dynamic dental diagnostic tool and its main features are compared with conventional laser luminescence for quantifying sound and defective enamel. A high-spatial- resolution dynamic experimental imaging set-up, which can provide simultaneous measurements of laser-induced frequency-domain IR photothermal radiometric and luminescence signals form defects in teeth, has been developed. Following optical absorption of laser photons, the new set-up can monitor simultaneously and independently the non-radiative conversion via IR photothermal radiometry; and the radiative de-excitation via luminescence emission.
