ABSTRACT:
A laser projection system is disclosed. The laser projection system includes a laser light source that is configured to selectively provide laser light. The system also includes an input beam deflection unit receiving the laser light and configured to deflect the laser light. The input beam deflection unit is configured to selectively change the angle of deflection of the laser light. A selection lens is also a part of the laser projection system and is configured to refract the laser light. A mask having at least one aperture is used. The mask receives the refracted laser light from the selection lens. A selected area of the mask is selectively illuminated by the refracted laser light. Further, a collection lens receives at least a portion of the laser light from the at least one aperture and refracts the portion of laser light. Further still, the laser projection system includes a redirection unit that receives the refracted portion of the laser light from the collection lens and the redirection unit deflects the portion of the laser light to a target.
