Paper Abstract

Fourier techniques are often used in optical processing for determining information about the diffracting objects. Many industrial powders are quasicircular and their diffraction patterns have a rotational symmetry. To classify automatically such diffracting samples we present an optical/digital spectrum analyzer which uses a Wedge Ring Detector. A procedure based on least-squares inversion of measurements is implemented to estimate particle-size distribution. A scene of three classes of varying sizes of Fe203, Fe0 particle substrate is analyzed and experimental results are given.
