This paper describes a technique for retrieving the size spectrum of an ensemble of aspherical particles from their preferential spatial orientation. Two basic mechanisms of particle orientation are considered. One of them has to do with aerodynamic forcing of particles moving in a viscous medium. The other stems from the interaction between the induced particle dipole moment and the electric field of the incident radiation. Quantitative estimates are presented for an ensemble of ellipsoidal particles.
