Abstract
An optical apparatus and an augmented reality device are provided. The optical apparatus includes an inner surface. The inner surface includes a predetermined region serving as a curved mirror with a predetermined optical parameter for reflection imaging of a virtual image of a virtual world. The optical apparatus further includes an outer surface. The outer surface and the inner surface are used for refraction imaging of a real image of a real world. The virtual image and the real image are integrated for forming a scene of augmented reality.
Claims8
An optical apparatus for a wearable augmented reality device, comprising:
- an inner surface, the inner surface being an irregular and aspherical surface and a surface of the optical apparatus that directly faces the user, wherein the inner surface comprises a predetermined region serving as a curved mirror with a predetermined optical parameter for reflection imaging of a virtual image of a virtual world;
- and
- an outer surface, the outer surface being an irregular and aspherical surface, wherein:
- an axis of the optical apparatus is parallel to a direction of observing the virtual world, the axis of the optical apparatus intersecting with the inner surface region serving as the curved mirror;
- the inner surface and the outer surface are used for refraction imaging of a real image of a real world, and the virtual image and the real image are integrated for forming a scene of augmented reality;
- a thickness between the inner surface and the outer surface is uneven;
- the predetermined region of the inner surface comprises an upper half portion of the inner surface and a lower half portion of the inner surface, one of the upper half portion of the inner surface and the lower half portion of the inner surface having a concave shape until the other one having a convex shape;
- and
- the outer surface comprises an upper half portion of the outer surface and a lower half portion of the outer surface, one of the upper half portion of the outer surface and the lower half portion of the outer surface having a concave shape until the other one having a convex shape, such that lens comprising the inner surface and the outer surface eliminate distortion for a user of the wearable augmented reality device and the user observes the scene of augmented reality at a focal point of the lens.
