Abstract
The S11 light scattering matrix element is a measurement of the total intensity of light scattered into a particular direction as a function of scattering angle. The S11 matrix element is peaked in the forward (specula') direction. Changes in the shape of the S11 curve may be used to detect the presence of micron-sized surface cracks in metals stretched beyond their elastic limit prior to failure. Shape changes are quantitatively monitored by studying changes in the kurtosis, or "flatness', of the Sii curve.
