    Abstract: Bright ambient light can wash out a virtual image in a conventional augmented reality device. Fortunately, this problem can be prevented with a variable electro-active beam splitter whose reflect/transmit ratio can be varied or switched on and off rapidly at a duty cycle based on the ambient level. As the ambient light gets brighter, the beam splitter's transmit/reflect ratio can be shifted so that the beam splitter reflects more light from the display and transmits less ambient light to the user's eye. The beam splitter can also be switched between a highly reflective state and a highly transmissive state at a duty cycle selected so that the eye spends more time integrating reflected display light than integrating transmitted ambient light. The splitting ratio and/or duty cycle can be adjusted as the ambient light level changes to provide the optimum experience for the user.

    Abstract: A conventional head-mounted display (HMDs) can display a virtual image at a fixed focus (e.g., infinite focus). If the user looks at an object that appears closer than the virtual image, then accommodation by the user's eyes will cause the virtual image to appear blurry. The HMDs disclosed herein include a dynamic electro-active focusing element that changes the focus of the virtual image to account for accommodation by the user. This dynamic electro-active focusing element may include a curved layer of electro-active material, such as nematic or bi-stable (e.g., cholesteric) liquid crystal, disposed between a static concave mirror and a convex surface on a beam splitter or other optical element. Changing the refractive index of the electro-active material causes the focus of the dynamic electro-active focusing element, making it possible to shift the virtual image's focus in as the user's eyes change focus.

    Abstract: An electro-active lens provides simultaneous focusing at two different optical powers. It does this with a stack of electro-active lens elements aligned along the same optical axis that each focus light in different polarization states (e.g., horizontal and vertical polarization states). If a first and second electro-active lens elements have different optical powers, light in a first polarization state can be focused to one optical power and light in a second polarization state can be focused to a different optical power simultaneously. The electro-active lens can be switched between different single and multiple optical powers. People with presbyopia may use the electro-active lens mounted in eyewear in place of conventional bifocal glasses. The electro-active lens may also be used in a scope to improve target aiming.

    Abstract: Transparent organic light-emitting diodes (OLEDs) can be used as light-emitting pixels in a near-eye display for augmented reality applications. The light from these pixels can be switchably tuned and/or steered with tunable beam-steering and focusing elements, also called tunable micro-lenses. These tunable micro-lenses are arranged in an array and mated to the array of pixels, for example, by embedding in a spectacle lens. The tunable micro-lenses use fast-switching half-wave plates to selectively focus and/or tilt light from the pixels. By switching the light from the pixels between resolvable positions/angles at a rate faster than the flicker fusion threshold (e.g., 60 Hz), the tunable micro-lenses can effectively double the apparent resolution of the near-eye display. And by switching between focusing and non-focusing states at the same rate, the tunable micro-lenses can effectively superimpose the virtual images from the pixels on the real-world image visible through the pixels.
