Curved waveguide

WebDescription of various see-through wearable display techniques using waveguides: Various techniques have existed for some time for See-through video wearable displays. Most of these techniques can be summarized into two main families: “Curved Mirror” based and “Waveguide” based. WebAn optical path-changing device having one or more curved waveguides according to an embodiment of the present invention includes a first waveguide (11) formed in a straight line. A second waveguide (12) is configured to branch from the first waveguide in a first direction and formed in a shape of curved line.
