Paper Abstract

Deconvolution of the complex diffraction patterns generated by laser inspection of a random array of fineparticles is a widely used method for characterizing the size distribution of the scattering fineparticles. Interpretive hypothesis used to deconvolute the diffraction pattern use simplified assumptions which usually ignore the diffracting effect of structural features of the fineparticle profiles. For quality control and processing research this is not a serious limitation of the methodology. However if one tries to use these methods to evaluate the size and concentration of respirable dust one must adjust the data processing involved in the deconvolution to take into account various structured features of the dust. In this communication the effect of sharp edges and fractal structure in respirable dust such as quartz, diesel exhausts, flyash and nuclear melt down fumes on the group diffraction pattern of a random array are discussed.
