Abstract
In this paper the beam steering theory in isotropic acousto-optic (AO) device is studied. In the process to design an AO deflector, it is important that the device has wider 3db Bragg bandwidth and uniform diffraction efficiency in frequency band. According to the theory about isotropic AO interaction, we can obtain wider 3db bandwidth by using technology of ultrasonic beam steering. It means, the momentum match condition can be satisfied at two track frequencies. The author gains the optimum track frequencies for various numbers of transducer pieces in plane and step configurations respectively. Based upon this argument, farther on, the optimum design parameter of the isotropic AO deflector is also shown up.
