Abstract
The phase-vector analysis enabled us to study the vectorial behavior of the light diffracted in the Fraunhofer plane by two adjacent antiparallel beams of progressive ultrasonic waves. It predicts also the vector angle, usually neglected, in addition to the light amplitude. Interesting frequency shifts superposed in some cases to a frequency modulation have been found if the ultrasonic frequency ratio F1/F2 equals m/n, with m, n small integers and m does not equal n. We present the results of the improved research, carried out by analyzing the light beam interacting with several wavelengths (Lambda) 0 equals m(Lambda) 1 equals n(Lambda) 2, to avoid the effects of the distortions of the diffraction lobes occurring if one wave (Lambda) 0 only is considered.
