Patent ID: 8582206

Claim:
A virtual-image projector comprising: a laser configured to form a narrow beam; first and second dilation optics, each one having a diffraction grating, the first dilation optic arranged to receive the narrow beam and to project a one-dimensionally dilated beam into the second dilation optic, the second dilation optic arranged to receive the one-dimensionally dilated beam and to project a two-dimensionally dilated beam; first and second redirection optics, each one operatively coupled to a transducer configured to pivot the redirection optic to which it is coupled, the first redirection optic arranged to direct the narrow beam into the first dilation optic at a first entry angle, the second redirection optic configured to direct the one-dimensionally dilated beam into the second dilation optic at a second entry angle; and a controller configured to bias the transducers to vary the first and second entry angles by pivoting the first and second redirection optics, and further configured to modulate an intensity of the laser in synchronicity with the first and second entry angles such that a virtual display image is formed and made visible through the second dilation optic.
