1. An optical display system comprising:
an optical waveguide combiner;
wherein said optical waveguide combiner comprises:
a waveguide optical substrate;
an optical input coupler on, in or adjacent said waveguide optical substrate; and
an optical output coupler on or in said a waveguide optical substrate, said optical input coupler being coupled via said waveguide optical substrate to said optical output coupler;
and
a plurality of cameras;
wherein said plurality of cameras comprises a first camera and a second camera;
wherein said first camera is optically coupled to the output coupler and has a first field of view of at least one virtual object displayable at an image plane by said optical waveguide combiner; the displayable virtual object(s) being in the field of view of an eyebox of the optical waveguide combiner;
wherein said second camera is optically coupled to the output coupler and has a second field of view of the virtual object(s) displayable by said optical waveguide combiner;
wherein, at the image plane, a combined field of view of the first camera and the second camera comprises the first field of view of the first camera and the second field of view of the second camera and includes an overlapping region of the first field of view and the second field of view; and
wherein, at the image plane, the displayable at least one virtual object is within the combined field of view of the first camera and the second camera.
