1. 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; and
an optical switch configured to be switched 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 reflective element and a first filter, and
when the optical switch is in the first mode:
the reflective element is configured to reflect the first-eye light to the first filter as first-eye reflected light, and
the first filter is configured to reflect a first portion of the second-eye light, to transmit a second portion of the second-eye light as a first portion of the combined light, and to reflect the first-eye reflected light as a second portion of the combined light.
