Abstract
A display system comprising an optical combiner. The optical combiner is arranged to form a surface for a first eye-box for a first user and a second eye-box for a second user and is transmissive. The display system further comprises a structure arranged in cooperation with a sub-area of the optical combiner. The structure is or appears substantially transmissive when viewed from the first eye-box and substantially opaque when viewed from the second eye-box.
Claims18
A display system comprising:
- an optical combiner arranged to form a surface for a first eye-box for a first user and a second eye-box for a second user, wherein the optical combiner is substantially transmissive;
- and
- a structure defining a sub-area of the optical combiner, wherein the structure of the sub-area of the optical combiner is (i) substantially transmissive when viewed from the first eye-box, thereby enabling the first user to both (i-a) see through the sub-area of the optical combiner and (i-b) view a hologram projected by a first holographic projector, and (ii) substantially opaque when viewed from the second eye-box, thereby enabling the second user to see a holographic reconstruction provided by a second holographic projector, wherein at least a portion of the holographic reconstruction appears in the sub-area of the optical combiner.
A method of display using an optical combiner arranged to form a viewing surface for a first eye-box for a first user and second eye-box for a second user, wherein the method comprises:
- forming a holographic reconstruction of a second picture on a structure arranged in cooperation with a sub-area of the optical combiner;
- and
- wherein the optical combiner is transmissive, and wherein the structure is (i) substantially transmissive when viewed from the first eye-box, thereby enabling the first user to both (i-a) see through the structure and (i-b) view a hologram projected by a first holographic projector, and (ii) substantially opaque when viewed from the second eye-box, thereby enabling the second user to see the holographic reconstruction of the second picture, wherein at least a portion of the holographic reconstruction appears on the structure.
