In optical diffraction particle sizing a numerical transform is sought so that a particle size distribution can be determined from angular measurements of near forward scattering. We consider the nonuniqueness and instability of this transform for discrete data. Our arguments are based on the approximation of the kernel by a function to which it is(More)
