    Abstract: A head-mounted display system including a contact lens having a first region and a second region adjacent the first region, an eyewear lens having an inner surface facing the contact lens, and an illuminator configured to produce an imaged light output directed toward the inner surface of the eyewear lens. A first imaged light ray produced by the illuminator is incident on the inner surface and is reflected by the eyewear lens to the first region. The first region is configured to transmit the first imaged light ray, and the second region is configured to reflect or absorb a second imaged light ray produced by the illuminator and reflected from the eyewear lens. The eyewear lens is configured to transmit an ambient light ray to the second region and the second region is configured to transmit the ambient light ray.

    Abstract: A lens 120 is formed from at least two sections or bodies 122, 124 that are shaped to mate with each other, and a multilayer optical film 125 is sandwiched between these two sections. Smooth surfaces 121a, 124a of each section combine to provide a first optical surface 120 a of the lens, e.g., a concave, convex, or flat optical surface. The multilayer optical film includes a stack of polymer layers configured to selectively reflect light by constructive or destructive interference, at least some of the polymer layers being birefringent. The multilayer optical film may thus be or comprise e.g. a reflective polarizer and/ or a narrow band or otherwise notched reflector. The multilayer optical film has an extended terminus 125tl that separates the smooth surfaces of the two sections. Any edge defects such as cracks or delaminations that may exist along the extended terminus are characterized by an average defect distance of no more than 100 or 50 microns.

    Abstract: Optical systems for displaying an image are described. The optical systems include a first and second optical lenses separated by air. A partial reflector is disposed on and conforms to a major surface of the first optical lens where the major surface can have a best-fit spherical radius of curvature in a range from 20 mm to 200 mm. A reflective polarizer is disposed on and conforms to a major surface of the first optical lens where the major surface can have a best-fit spherical radius of curvature greater than about 500 mm. A retarder layer is disposed between the reflective polarizer and the partial reflector. The first optical lens can have an optical birefringence of less than 15 nm/cm and the second optical lens can have an optical birefringence of greater than 15 nm/cm. A method of fabricating an optical assembly is described.

    Abstract: A polarizing beam splitting system is described. The polarizing beam splitting system may include first and second prisms where the volume of the first prism is no greater than half the volume of the second prism. The first prism includes first and second surfaces and a light source may be disposed adjacent the first surface and an image forming device may be disposed adjacent the second surface. The first prism has a first hypotenuse and the second prism has a second hypotenuse. A reflective polarizer is disposed between the first and second hypotenuses.

    Abstract: An image combiner, also referred to as a combiner optic, of a near-eye display system or the like transmits enough light so a user can see remote objects in a "world view", while also reflecting enough light so the user can simultaneously see a projected image in a "projected" (augmented) view. The disclosed image combiners use two partial reflectors configured to form a wedged reflective cavity. In the display system, light from an imaging device follows a path to the user's eye that includes three reflections in the wedged cavity. By using this capability of the wedged cavity, the combiner optic can have a substantially reduced thickness, and lower profile, than a combiner optic that uses only one partial reflector and only one reflection in the optical path.
