Patent ID: 7136084

Claim:
A laser projection system comprising: a laser light source configured to selectively provide laser light having a diameter; a single input beam deflector receiving the laser light and configured to deflect the laser light, the single input beam deflector configured to selectively change the angle of deflection of the laser light, the single input beam deflector having two degrees of freedom of motion; a selection lens configured to refract the laser light; a mask having at least one aperture, the mask receiving the refracted laser light from the selection lens, a selected area of the aperture being selectively illuminated by the refracted laser light; a collection lens receiving at least a portion of the laser light from the at least one aperture and refracting the portion of the laser light; a single redirector, the single redirector having two degrees of freedom of motion, the single redirector receiving the refracted portion of the laser light from the collection lens and the single redirector being configured to deflect the portion of the laser light; wherein the aperture includes a length that is much greater than the diameter of the laser light to create projected shapes with a varying height depending on the selected area of the aperture being selectively illuminated by the refracted laser light.
