Mems projector using multiple laser sources

A method for projecting an image through a MEMS laser scanning projector, comprising:

• projecting a first laser beam from a first laser source;
• projecting a second laser beam from a second laser source at an angle with respect to the first laser beam;
• and
• using a mirror to alternate between:
• simultaneously reflecting the first and second laser beams to scan in a first scan pattern to form a first image, and
• simultaneously reflecting the first and second laser beams to scan in a second scan pattern to form a second image;
• wherein the first and second images each have a number of scan lines greater than two times a horizontal resonance frequency at which the mirror oscillates divided by a desired frame rate of the first image;
• wherein the first laser beam forms a first angle of incidence with the mirror and the second laser beam forms a second angle of incidence, the second angle of incidence being equal to the first angle of incidence summed to the angle of the second laser beam with respect to the first laser beam.

An electronic device, comprising:

• a first laser source configured to project a first laser beam;
• a second laser source configured to project a second laser beam in alignment with the first laser beam in a first direction but at an angle with respect to the first laser beam in a second direction;
• a mirror apparatus positioned so as to simultaneously reflect the first and second laser beams;
• and
• control circuitry configured to alternate between:
• controlling the mirror apparatus to scan the simultaneously reflected first and second laser beams in a first scan pattern;
• and
• controlling the mirror apparatus to scan the simultaneously reflected first and second laser beams in a second scan pattern, the second scan pattern being different than the first scan pattern.

A method, comprising:

• projecting a first laser beam from a first laser source and at a same time as projecting a second laser beam from a second laser source, with the second laser beam being projected at an angle with respect to the first laser beam;
• simultaneously receiving the first and second laser beams at a mirror such that the first laser beam forms a first angle of incidence with the mirror and such that the second laser beam forms a second angle of incidence with the mirror different than the first angle of incidence;
• and
• causing the mirror to alternate between reflecting the first and second laser beams to scan in a first scan pattern to form a first frame and reflecting the first and second laser beams to scan in a second scan pattern to form a second frame different than the first frame.

A MEMS laser scanning projector, comprising:

• a first laser source configured to project a first laser beam;
• a second laser source configured to project a second laser beam at an angle with respect to the first laser beam;
• a mirror apparatus positioned so as to simultaneously reflect the first and second laser beams;
• and
• control circuitry configured to control the mirror apparatus to scan the simultaneously reflected first and second laser beams in a first scan pattern to form a first image at a first time and to scan the simultaneously reflected first and second laser beams in a second scan pattern to form a second image at a second time after the first time;
• wherein the first laser beam forms a first angle of incidence with the mirror apparatus and the second laser beam forms a second angle of incidence with the mirror apparatus, the second angle of incidence being equal to the first angle of incidence summed to the angle of the second laser beam with respect to the first laser beam.
