ABSTRACT:
A volume diffractive composite is disclosed for providing illumination at a first output angle. The volume diffractive composite comprises a first plurality of grating elements that are mutually spaced from another in a first position with a first spacing period along a first plane, and an actuation unit for changing at least one of the position or the spacing period of the first plurality of grating elements to a second position or spacing period to provide illumination at a second output angle.
