Popis: The dynamics of light scattering and internal force in cartilage in vitro are studied in the course of laser shaping. In experiments were used the samples of human cartilage which were collected from patients who underwent nasal septum stirgely. We found that the dynamic of scattered light intensity depends on heating rate and on the temperature of the sample. The sign of the derivative of the scattered light intensity changes when phase transition is occur. The stress force changes during laser heating and relax after action to much less value than it was before laser treatment. Histological investigation allow us to correlate the dynamics of optical and mechanical properties of cartilage with stable and nondestructive reshaping regimes.
