Abstract
A light projection system includes an angle-dependent pattern projection device projecting light of multiple patterns into corresponding multiple directions, and a waveguide comprising an input and an output, configured to accept the light from the angle-dependent pattern projection device and emit the light through the output, whereby the light from each of the multiple patterns takes a unique path through the waveguide. The waveguide is built into a headset display device, and the output of the waveguide couples light emitted through the output to an eye.
