Claim 13:
14. A method of image projection comprising:
emitting a first-eye light by a first light source, wherein the first-eye light includes a first set of wavelengths;
emitting a second-eye light by a second light source, wherein the second-eye light includes a second set of wavelengths;
receiving a first input light by a first projector including first projection optics; and
switching an optical switch between a first mode and a second mode,
wherein the optical switch is configured to, in the first mode, combine the first-eye light and the second-eye light into a combined light and direct the combined light to the first projection optics as the first input light, wherein
the optical switch includes a first filter and a reflective element, and
switching the optical switch to the first mode comprises:
moving the first filter to a first position, so as to allow the first-eye light and the second-eye light to pass to the first projection optics as the combined light.
