Classification: CPC G  H | IPC G  H

Claim 16:
17. A non-transitory computer-readable medium storing instructions that, when executed by a processor of a projection device, cause the projection device to perform a set of operations comprising:
controlling a first light source to emit a first-eye light, wherein the first-eye light includes a first set of wavelengths;
controlling a second light source to emit a second-eye light, wherein the second-eye light includes a second set of wavelengths;
controlling a first projector to receive a first input light, the first projector including first projection optics; and
controlling an optical switch to switch between a first mode and a second mode,
wherein the optical switch, in the first mode, combines the first-eye light and the second-eye light into a combined light and directs 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
controlling the optical switch to switch to the first mode comprises:
controlling the reflective element to move to a first position, so as to reflect the first-eye light to the first filter as first-eye reflected light, and
causing the first filter 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.
