Abstract
Abstract An acousto-optic beam deflector comprises an optically active stress optic medium (10), such as crystalline quartz, driven by a longitudinal acoustic wave transducer (12). The deflector is independent of optical polarization, and therefore both polarization components of an input optical beam, such as a laser beam, are scattered with equal efficiencies.
