    Abstract: Disclosed are a zoom lens, a zoom method and a terminal. The zoom lens includes n lens groups, n reflecting elements and n imaging planes, where n is an integer greater than or equal to 2. The n lens groups and an n-th imaging plane are arranged sequentially along an optical axis. A first reflecting element is configured to receive and reflect first incident light to a first lens group. An i-th imaging plane is arranged between an i-th lens group and an (i+1)-th lens group, where i is an integer greater than or equal to 1 and less than n. A j-th reflecting element is disposed between a (j−1)-th lens group and a j-th lens group, and is configured to be moved and/or rotated to enable the zoom lens to zoom, where j is an integer greater than 1 and less than or equal to n.

    Abstract: Various exemplary systems for transporting and switching optical components are disclosed. The system includes carriers disposed about a housing and configured to follow a carrier guide system to switch optical components at the optical prescription center of the optical path. In one example, a device is disclosed that reduces the packaging form factor through the use of carriers rotated about an inverted radius along a track adjacent to a limiting peripheral boundary. The system and device are configured to switch optical components while minimizing the form factor of the optical device. Methods of accomplishing these tasks are also disclosed.

    Abstract: Architecture and designs of wearable devices for viewing multimedia in 3D are described. According to one aspect of the present invention, a display device is made in form of a pair of glasses. A separate enclosure is provided to generate content for display on the glasses. The content is optically picked up by an optical cable and transported by one or more optical fibers in the optical cable to the glasses, where an image polarizer receives the content and produces an alternating polarized content sequence. An optical cube is provided to decouple the alternating polarized content sequence into two orthogonally polarized image sequences are respectively projected onto two lenses.
