Abstract
A leaky-mode acousto-optical modulator may be used to generate visual images suitable for direct viewing, without image-forming optics. To extend a field of view of the modulator to limits suitable for visual displays, an array of acoustic transducers is coupled to a waveguide along its length. Each acoustic transducer generates an acoustic wave causing a corresponding leaky mode to appear. A reflector is disposed proximate each transducer for directing the out-coupled light portion at a unique angle, providing a corresponding field of view portion for that direction. The field of view portions coalesce into a continuous synthetic field of view suitable for wide-angle visual display applications.
