Abstract:
There is provided a laser projector, including: a laser source section for emitting laser beams; a spatial light modulator which modulates the laser beams to generate image light; a projector lens from which the image light is emitted; a beam shaper which shapes the laser beams into a shape of the spatial light modulator; and a pupil uniformizer which makes a light intensity distribution uniform at an exit pupil of the projector lens, wherein the pupil uniformizer is situated between the laser source section and the beam shaper.
