US Patent 12066622 Projector architecture incorporating artifact mitigation

An eyepiece for projecting an image includes a first planar waveguide positioned in a first lateral plane. The first planar waveguide comprises a first diffractive optical element (DOE) disposed at a first lateral position. The eyepiece also includes a second planar waveguide positioned in a second lateral plane adjacent to the first lateral plane. The second planar waveguide comprises a second DOE disposed at a second lateral position different from the first lateral position. The eyepiece further includes a third planar waveguide positioned in a third lateral plane adjacent to the second lateral plane. The third planar waveguide comprises a third DOE disposed at a third lateral position different from the first lateral position and the second lateral position. The eyepiece also includes an optical filter positioned between the second planar waveguide and the third planar waveguide. The optical filter is disposed at the third lateral position.
