Abstract
An acousto-optic device is disclosed. The device comprises: an optically transmissive element to receive a beam of light at an input surface, the beam being received from a direction defining an optical axis; a set of acoustic transducers spaced around the element; and a controller operable to activate the transducers to generate an acoustic wave travelling through the device to intersect with the optical axis. The controller is further operable to selectively activate a first subset of the set of transducers such that the acoustic wave propagates in a selected direction. Each of the set of acoustic transducers is differently orientated such that the selected direction is controllable through the selection of first subset of transducers from the set of transducers, and the device is thereby operable to control the direction in which the beam of light is deflected in two dimensions. A method of operating the device is also disclosed.
