Abstract
Acousto-optical modulators, such as a SAW modulators, with telescope arrays and superimposed volume gratings for light field generation are disclosed. These devices can employ pixelated demagnification and have layers of output optics, such as reflective gratings and/or arrays of transmissive refractive or diffractive lenses that manipulate the light emitted by the SAW modulator. In other cases, superimposed volume gratings are used, in which pixilation occurs in angle space.
