Abstract

Light transmitted by thin slabs of human dental enamel is scattered and Fraunhofer diffracted. At three wavelengths we used the two dimensional transmitted Fraunhofer diffraction patterns to determine the periodicity of the prism structure and the curvature and misalignment of the prisms. This was performed by fitting theoretical curves to measured intensity functions. We found for each sample a mean value of the periodicity and its standard deviation. The deviation between the mean values found at each wavelength was much smaller than the deviation of the size distribution in each sample. The measured overall mean value of the periodicity and its standard deviation was d equals 4.9 plus or minus 0.6 micrometer. The mean angle of curvature and misalignment was (Delta) (phi) equals 32 degrees plus or minus 22 degrees.
