Abstract
The invention relates to a laser projector for presenting an image on a waveguide plane. The projector comprises a laser source (A,B,C) capable of emitting a polychromatic light beam () or a plurality of narrow-wavelength light beams (A,B,C), and a guidance element (A,B) for directing light emitted by the light source to different pupils (A,B,C) of the waveguide plane, the different pupils being displaced with respect to each other in the waveguide plane. The invention also concerns a personal display device comprising such projector.
