Assignee: MAGIC LEAP, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An image projection system, comprising:
an optical subsystem for emitting a modulated light beam, wherein the modulated light beam is modulated according to a plurality of image fields in sequence;
a scanning mirror positioned to intercept the modulated light beam and generate a reflected light beam, wherein the scanning mirror includes an actuator configured to adjust an orientation of the scanning mirror according to a sequence of scan patterns, wherein the sequence of scan patterns corresponds 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; and

projection optics positioned to receive the reflected light beam and project a plurality of images in sequence, wherein each image of the plurality of images comprises multiple image fields of the plurality of image fields;
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.
