Classification: CPC G | IPC G

Claim 10:
11. An optical system comprising:
a scanning mirror operable to rotate around an axis;
a pupil separation system comprising:
an input surface;
a central portion including a set of dichroic mirrors;
a first reflective surface disposed laterally with respect to the central portion; and
a second reflective surface disposed laterally with respect to the central portion;
an output surface including:
a central surface operable to transmit light in a first wavelength range;
a first peripheral surface adjacent the central surface and operable to transmit light in a second wavelength range; and
a second peripheral surface adjacent the central surface and opposite to the first peripheral surface, wherein the second peripheral surface is operable to transmit light in a third wavelength range;

an eyepiece waveguide including:
a first waveguide layer including a first incoupling grating (ICG) corresponding to the first wavelength range;
a second waveguide layer including a second ICG corresponding to the second wavelength range, wherein the second ICG is spatially offset from the first ICG; and
a third waveguide layer including a third ICG corresponding to the third wavelength range, wherein the third ICG is spatially offset from the first ICG and the second ICG.
