摘要: A shaped reflective polarizer has different maximum sags in different directions and has an interior portion rotationally symmetric about a principle axis and a peripheral portion adjacent the interior portion and rotationally asymmetric about the principle axis. An optical system includes a partial reflector and an optical stack including an optical lens and the shaped reflective polarizer disposed on a curved major surface of the optical lens. The optical lens may have a contoured edge adapted to be placed adjacent an eye of a viewer and substantially conform to the viewer's face.

摘要: An eye tracking device for integrating in a frame for mounting to a user's head includes a laser output unit for fixing to the frame. The laser output unit is configured to provide a laser beam for illuminating a cornea of the user's eye when in use. The eye tracking device also includes a receiver unit for fixing to the frame. The receiver unit is configured to receive a reflection of the laser beam and to provide a tracking signal usable for determining a distance or velocity of the cornea. The eye tracking device further includes a processing unit for determining a rotation of the user's eye from the tracking signal.

摘要: An electronic device may provide foveated images at an eye box. The device may have a first display module that produces a low resolution portion of the image and a second display module that produces a high resolution portion of the image. A reflective input coupling prism may be mounted to a waveguide. A steering mirror may overlap the prism. The mirror may receive the high resolution portion through the waveguide and the prism. The mirror may reflect the high resolution portion back into the waveguide and may be adjusted to shift a location of the high resolution portion within the image. For example, the steering mirror may adjust the position of the high resolution portion to align with the gaze direction at the eye box. A reflective surface of the prism may reflect the low resolution portion of the image into the waveguide.

摘要: A glass laminate (100) including first and second glass layers (102,104), a reflective film (110) having opposed first and second major surfaces and disposed between the first and second glass layers (102,104) with the first and second major surfaces facing the respective first and second glass layers (102,104), a first adhesive layer (117) disposed between and bonding together the first glass layer (102) and the reflective film (110), and a second adhesive layer (119) disposed between and bonding together the second glass layer (104) and the reflective film (110) is described. The second adhesive layer (119) is thicker than the first adhesive layer (117) such that the first major surface of the reflective film (110) is separated from an outermost major surface of the first glass layer (102) by distance d1, the second major surface of the reflective film (110) is separated from an outermost major surface of the second glass layer (104) by a distance d2, and 0.05

摘要: Systems, methods, and apparatuses are provided herein for changing the positions and/or shapes of microlenses of a light field camera to generate light field images with enhanced depth of field and/or dynamic range. This may be accomplished by a light field camera determining a plurality of focus measurements for a plurality of microlenses, wherein one or more of the plurality of microlenses vary in distance from a main lens of the light field camera. The light field camera may use the plurality of focus measurements to determine a microlens of the plurality of microlenses that captures information that is the most focused. The light field camera can then determine defocus functions for the microlenses that are not capturing information that is the most focused. The light field camera can then generate a light field image using the determined defocus functions and the information captured by the plurality of microlenses.

摘要: A head mounted display system for displaying image content to a user comprises at least one display configured to be worn by a user to present virtual content to first and second eyes of a user, one or more inwardly facing sensors or camera configured to monitor one or both of the users eye and processing electronics. This head mounted display system is configured such that virtual content activity can be initiated and/or driven from eye inputs such as gaze direction, eyelid motions (e.g., blinking), and/or other eye gestures.
