1. An optical system including a generally planar waveguide having an input edge and a planar extent along which light can propagate by total internal reflection away from the edge, and a source of modulated light arranged to inject light rays into the input edge at a range of out-of-plane angles, the waveguide being constituted as a light-ejecting waveguide such that rays entering at different out-of-plane angles leave the ejecting waveguide, instead of being totally internally reflected, at different respective points along the direction of propagation in the waveguide.
