Abstract
The statistical characteristics of the dynamic speckle fields associated with the scattering of coherent emission on a cartilaginous tissue during its thermal modification by laser irradiation were studied. A method for determining the energy of activation of the thermally induced processes of structural modification of scattering sites was suggested; the method is based on an analysis of the scattered light flashing index. For cartilaginous tissue, the activation energy was estimated as ≈63 kJ/mol, a value that may characterize conformational transitions in the subsystem of proteoglycan aggregates.
