A method for solving the inverse-scattering problem empirically is introduced. The method is called the strip-map technique, and, for now, we restrict its use to the identification of single homogeneous spherical particles. First the technique is illustrated in a <i>gedanken</i> experiment with an ideal spherical microparticle. Then the technique is applied to the study of four particles from which light-scattering data have been collected. Nonspherical or inhomogeneous spherical particles are immediately distinguished from particles that are homogeneous spheres, the latter being specified to a high degree of precision. The technique can be made extremely rapid: with modest computer means, individual microparticles can be characterized in less than 1 msec.
