Classification: CPC G  H | IPC G  H

Claim 13:
14. A method for projecting an image, the method comprising:
generating a modulated light beam, wherein the modulated light beam is modulated according to a plurality of image fields in sequence;
illuminating a scanning mirror with the modulated light beam to generate a reflected light beam; and
projecting the reflected light beam to generate a plurality of images, wherein each image of the plurality of images is generated by projecting multiple image fields of the plurality of image fields in sequence, and wherein projecting each image field of the plurality of image fields includes adjusting an orientation of the scanning mirror according to a sequence of scan patterns corresponding to:
a randomly selected scan pattern sequence of a plurality of different scan patterns;
a pseudo-randomly selected scan pattern sequence of the plurality of different scan patterns; or
a quasi-randomly selected scan pattern sequence of the plurality of different scan patterns;

wherein each scan pattern of the sequence of scan patterns is (i) randomly selected, pseudo-randomly selected, or quasi-randomly selected from a fixed number of different scan patterns in the plurality of different scan patterns, and is (ii) phase shifted relative to each other scan pattern of the plurality of different scan patterns.
