FIG. 1.

(a) Time-lapse SHG images of chicken skin dermis acquired during isothermal denaturation at . (b) Time dependences of dermis shrinkage (1) and collagen fiber SHG intensity (2). The solid line is the result of the single exponential fit to the SHG intensity decay.

Image of FIG. 2.
FIG. 2.

Temperature profile (1) and the SHG intensity (2) in chicken skin dermis. Exponential fittings of the SHG signal decay at two temperatures (57.1 and ) are plotted as solid lines.

Image of FIG. 3.
FIG. 3.

The use of the plot of vs for the determination of the activation energy and frequency factor of collagen denaturation in dermis. Kinetic data obtained at 12 temperatures (from 54.5 to ) were used.

Image of FIG. 4.
FIG. 4.

Time-lapse SHG images of collagen fibers in (a) reticular dermis and (b) papillary dermis of chicken skin acquired during the thermal treatment. Experimental (1) and calculated (2) SHG intensity decays are respectively shown in (c) and (d). The temperature history of the samples (curves 3) are also shown.
