  • Publication number: 20150378307
    Abstract: A holographic reproducing apparatus includes: a photorefractive crystal configured to have holographic images recorded in a plurality of different angles respectively; and a light source configured to supply a plurality of reproducing light beams to be incident to the photorefractive crystal in different angles, wherein the reproducing light beams have a same frequency and a same optical length as a reference light beam used when the holographic images are formed. In the holographic reproducing apparatus, each of the holographic images can be presented in different angles without interference therebetween, so that observers in a plurality of orientations can view the holographic images recorded in the photorefractive crystal, thus the problem that the viewing angle is unique in the holographic reproducing procedure is addressed.

  • Publication number: 20150286062
    Abstract: The present invention provides a cylindrical lens assembly, comprising a cylindrical lens array, a closed hood and a liquid storage tank. A to-be-filled chamber is formed between the cylindrical lens array and the closed hood. The to-be-filled chamber is connected with the liquid storage tank used for storing transparent liquid. The refractive index of the transparent liquid is the same as that of the cylindrical lens array. The transparent liquid can flow between the liquid storage tank and the to-be-filled chamber and fill up the to-be-filled chamber. The top of the closed hood is made of a transparent material. The present invention further provides a display device comprising above cylindrical lens assembly. The cylindrical lens assembly provided by the present invention is simple and easy to operate, and the display device comprising above cylindrical lens assembly can realize a switchover between flat panel display and stereoscopic display, with low cost.

  • Patent number: 9059834
    Abstract: The invention relates to a method and algorithm for stabilizing the output state of an optical transceiver. The method includes comparing a signal quality monitor (SQM) register value with a predetermined threshold. If the SQM register value is less than or equal to the predetermined threshold, a microcontroller unit (MCU) reads and determines the rx_lol state bit value of a clock and data recovery (CDR) chip. If the rx_lol state bit value reaches a low logic level value at least 3 times, the MCU converts the state bit values of rx_lol and mod_nr into low logic level values, or else, convert the state bit values of rx_lol and mod_nr into high logic level values. If the SQM register value is greater than the predetermined threshold then the state bit values of rx_lol and mod_nr will be left unchanged. When there is no data input to the CDR chip, the method of the present invention will maintain rx_lol and mod_nr at high or low logic level values to stabilize the output state of the optical transceiver.

  • Publication number: 20140198360
    Abstract: Devices and methods for recording and reproducing a holographic 3D image are provided. The devices for recording the holographic 3D image comprising: a laser generation unit for emitting a laser beam; a beam splitter unit configured to receive the laser beam from the laser generation unit and split the laser beam into a reference beam and an object beam directed to an object to be photographed; a photorefractive crystal configured to receive the reference beam from the beam splitter and the object beam diffused from the object to form a holographic 3D image; and a rotation unit configured to rotate the photorefractive crystal once every time one holographic 3D image is recorded. The holographic 3D image can be recorded and reproduced by the rotate the photorefractive crystal in light paths of recording and reproduction light beams, respectively.
