Abstract

Techniques for operating an optical system are disclosed. World light may be linearly polarized along a first axis. When the optical system is operating in accordance with a first state, a polarization of the world light may be rotated by 90 degrees, the world light may be linearly polarized along a second axis perpendicular to the first axis, and zero net optical power may be applied to the world light. When the optical system is operating in accordance with a second state, virtual image light may be projected onto an eyepiece of the optical system, the world light and the virtual image light may be linearly polarized along the second axis, a polarization of the virtual image light may be rotated by 90 degrees, and non-zero net optical power may be applied to the virtual image light.

Claims (38)

1 . An optical system comprising:

a projector configured to emit light;

at least one waveguide optically coupled to the projector and configured to receive and redirect light therefrom toward a user;

a shutter assembly comprising at least one component positioned adjacent to the at least one waveguide, wherein the shutter assembly is controllable to allow a variable amount of ambient light from an environment of the user to pass therethrough toward the user;

an adaptive lens assembly positioned between the at least one waveguide and the user, wherein the adaptive lens assembly is controllable to impart a variable amount of optical power to light passing therethrough toward the user; and

control circuitry communicatively coupled to the projector, the shutter assembly, and the adaptive lens assembly, wherein the control circuitry is configured to synchronously:

cause the adaptive lens assembly to vary an amount of optical power imparted to light passing therethrough toward the user; and

cause the shutter assembly to vary the amount of ambient light from the environment of the user allowed to pass therethrough toward the user inversely with the amount of optical power imparted by the adaptive lens assembly to light passing therethrough.

2 . The optical system of claim 1 , wherein the at least one waveguide is further configured to allow ambient light from the environment of the user to pass therethrough toward the user.

3 . The optical system of claim 1 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the environment of the user.

4 . The optical system of claim 1 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the user.

5 . The optical system of claim 1 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the adaptive lens assembly.

6 . The optical system of claim 1 , wherein the at least one waveguide comprises a plurality of waveguides.

7 . A method of operating an optical system, the method comprising:

emitting light by a projector;

receiving and redirecting, by at least one waveguide optically coupled to the projector, light from the projector toward a user;

controlling a shutter assembly comprising at least one component positioned adjacent to the at least one waveguide to allow a variable amount of ambient light from an environment of the user to pass therethrough toward the user;

controlling an adaptive lens assembly positioned between the at least one waveguide and the user to impart a variable amount of optical power to light passing therethrough toward the user; and

using control circuitry communicatively coupled to the projector, the shutter assembly, and the adaptive lens assembly to synchronously:

cause the adaptive lens assembly to vary an amount of optical power imparted to light passing therethrough toward the user; and

cause the shutter assembly to vary the amount of ambient light from the environment of the user allowed to pass therethrough toward the user inversely with the amount of optical power imparted by the adaptive lens assembly to light passing therethrough.

8 . The method of claim 7 , wherein the at least one waveguide is further configured to allow ambient light from the environment of the user to pass therethrough toward the user.

9 . The method of claim 7 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the environment of the user.

10 . The method of claim 7 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the user.

11 . The method of claim 7 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the adaptive lens assembly.

12 . The method of claim 7 , wherein the at least one waveguide comprises a plurality of waveguides.

13 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

causing a projector to emit light, wherein at least one waveguide optically coupled to the projector is configured to receive and redirect the light from the projector toward a user;

controlling a shutter assembly comprising at least one component positioned adjacent to at least one waveguide to allow a variable amount of ambient light from an environment of the user to pass therethrough toward the user;

controlling an adaptive lens assembly positioned between the at least one waveguide and the user to impart a variable amount of optical power to light passing therethrough toward the user; and

using control circuitry communicatively coupled to the projector, the shutter assembly, and the adaptive lens assembly to synchronously:

cause the adaptive lens assembly to vary an amount of optical power imparted to light passing therethrough toward the user; and

cause the shutter assembly to vary the amount of ambient light from the environment of the user allowed to pass therethrough toward the user inversely with the amount of optical power imparted by the adaptive lens assembly to light passing therethrough.

14 . The non-transitory computer-readable medium of claim 13 , wherein the at least one waveguide is further configured to allow ambient light from the environment of the user to pass therethrough toward the user.

15 . The non-transitory computer-readable medium of claim 13 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the environment of the user.

16 . The non-transitory computer-readable medium of claim 13 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the user.

17 . The non-transitory computer-readable medium of claim 13 , wherein the at least one component of the shutter assembly comprises at least one component positioned between the at least one waveguide and the adaptive lens assembly.

18 . The non-transitory computer-readable medium of claim 13 , wherein the at least one waveguide comprises a plurality of waveguides.
