Abstract
We present the technique of laser Rayleigh scattering imaging (LRSI),which has been used for the mapping of inhomogeneities and point defectsin sapphire test masses for laser interferometer gravitational wave detectors.We analyse the errors associated with side wall mapping of cylindrical testmasses, and present the comparison of two samples which show significantdifferences. The technique could be used to improve quality control in themanufacture of optical materials.
