Abstract

A light pulse and a sound pulse, each consisting of a fundamental tone and its N-1 harmonics, influence each other by means of the acousto optical interaction. The optical near field intensity pattern, where all the diffracted light beams still overlap and interfere with each other, contains all the information of the sound pulse. We show that, for a given light pulse, one can reconstruct out of this optical near field, all the frequencies, amplitudes and phases of the sound pulse.
