Claim 8:
9. A projection system, comprising:
a first light source configured to emit a first-eye light, wherein the first-eye light includes a first set of wavelengths;
a second light source configured to emit a second-eye light, wherein the second-eye light includes a second set of wavelengths;
a first projector including first projection optics configured to receive a first input light;
an optical switch configured to be switched between a first mode and a second mode; and
a second projector including second projection optics configured to receive a second input light,
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,
wherein, when the optical switch is in the first mode:
the first filter is configured to allow the first-eye light and the second-eye light to pass to the first projection optics as the combined light, and

wherein, when the optical switch is in the second mode:
the first filter is configured to reflect the first-eye light and a first portion of the second-eye light to the reflective element as first-eye reflected light, and to transmit a second portion of the second-eye light as the first input light, and
the reflective element is configured to direct the first-eye reflected light to the second projector.
