Adjustable scanned beam projector

Examples are disclosed herein relating to an adjustable scanning system configured to adjust light from an illumination source on a per-pixel basis. One example provides an optical system including an array of light sources, a holographic light processing stage comprising, for each light source in the array, one or more holograms configured to receive light from the light source and diffract the light, the one or more holograms being selective for a property of the light that varies based upon the light source from which the light is received, and a scanning optical element configured to receive and scan the light from the holographic light processing stage.
