Abstract
A projection system and method therefor comprises 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 an 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.
Claims18
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.
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.
