GENERATING A VIRTUAL CONTENT DISPLAY
First Claim
1. A method of generating a virtual image, comprising:
- directing a light beam to a first side of an eyepiece, including transmitting the light beam into a first waveguide of the eyepiece;
deflecting, by one or more first diffractive elements of the first waveguide, a first portion of the light beam towards a second waveguide of the eyepiece, the first portion of the light beam associated with a first phase of light;
deflecting, by two or more protrusions positioned on the first side of the eyepiece, a second portion of the light beam towards the second waveguide of the eyepiece, the second portion of the light beam associated with a second phase of light differing from the first phase; and
deflecting, by one or more second diffractive elements of the second waveguide, some of the first and the second portions of the light beam to provide an exiting light beam associated with the virtual image, the exiting light beam based on the first and the second phases.

8. An optical projection eyepiece comprising:
-
a first side configured to receive a light beam; first and second waveguides, the first waveguide including one or more first diffractive elements configured to deflect a first portion of the light beam towards the second waveguide, the first portion of the light beam associated with a first phase of light; and two or more protrusions positioned on the first side of the eyepiece and arranged to deflect a second portion of the light beam towards the second waveguide of the eyepiece, the second portion of the light beam associated with a second phase of light differing from the first phase; wherein the second waveguide includes one or more second diffractive elements configured to deflect some of the first and the second portions of the light beam to provide an exiting light beam associated with a virtual image and based on the first and the second phases. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
