Multi-plane projection with laser beam scanning in augmented reality displays

The invention relates to multi-plane projection with laser beam scanning in augmented reality displays. An image projection system includes a first emitter configured to generate a first light beam; a first collimating lens configured to receive the first light beam and generate a first collimated light beam to be projected onto the eye to render a first projection image perceived at a first projection plane; a second emitter configured to generate a second light beam; a second collimating lens configured to receive the second light beam and to generate a second collimated light beam to be projected onto the eye to render a second projection image perceived at a second projection plane; a first beam combiner configured to transmit the first collimated beam and the second collimated beam on a combined transmission path; and a scanner configured to divert the first collimated light beam and the second collimated light beam according to a scan pattern to render the first projection image and the second projectio
