Paper Abstract

Harnessing phased acoustic arrays for extending the operating range of optical deflectors is well known and investigated by a number of researchers. Usually, it was supposed, that acoustic waves are excited in contra-phase, or with phase difference linear dependent on wave frequency. These modes of excitation are easily achieved in deflectors of simple design, but they do not provide strict consistency between acoustic wave front and Bragg angle when scanning the optical beam. To investigate possibilities of multielement deflector with individual control of channels in phased acoustic array we examined light diffraction on a sequence of ultrasonic waves in isotropic medium.
