摘要： An optical waveguide apparatus (30) comprises at least two total internal reflection TIR surfaces and containing a grating with fringes (31) disposed at ninety degrees to the waveguide TIR surfaces and slanted within a waveguide plane to provide a beam deflection angle within the waveguide plane; wherein an input TIR light comprises upward TIR light and downward TIR light diffracted respectively in at least first and second ranges of diffraction angles; the input TIR light with a first angular range along a first propagation direction undergoes at least two diffractions, wherein each ray from said first angular range and its corresponding diffracted ray lie on the diffraction cone of said grating, wherein each diffraction provides a unique TIR angular range along a second propagation direction.

摘要： An optical waveguide comprises at least two TIR surface and contains a grating. Input TIR light with a first angular range along a first propagation direction undergoes at least two diffractions at the grating. Each diffraction directs light into a unique TIR angular range along a second propagation direction.
