Abstract: Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof.

Abstract: A multi-view image display system provides a plurality of multi-view three-dimensional (3-D) images, using the mask type of image arrangement plate where the images grouped by corresponding pixels are arranged in a same order as that of the pixels. Each pixel cell is provided with an image display region which is divided into a plurality of subcells arranged depending on arrangement structure of the viewing zones, and each of the subcells transmits or reflects the lights from point light sources using its whole area, thereby allowing the transmitted or reflected lights to be collected in each of the viewing zones to form each of the view images.

Abstract: An optical sensing apparatus for use in a ring laser interferometer measuring a physical quantity of an object includes a ring laser cavity formed by several internal mirrors, of which at least two internal mirrors are partly light-transmitting. The ring laser cavity generates two laser beams of an identical wavelength, the two laser beams propagating in counter direction to each other in the ring laser cavity. External mirrors are disposed at a distance from the ring laser cavity, whereby portions of the two laser beams, which pass through the internal mirrors and travel on optical paths toward the external mirrors, are reflected back into the ring laser cavity. The apparatus further includes at least one platform for mounting the external mirrors.

Abstract: A multiview three-dimensional image display system comprises an image projection screen, two image generation components, a bifold mirror, an spatial light modulator, and projection optics. Each of the image generation components generates successive finite time sequences of time-multiplexed multiview images and thus form a channel of multiview images. Each of the reflecting surfaces of the bifold mirror reflects a different one of the two channels of multiview images. The spatial light modulator comprises a plurality of strip-like shutters, each of which transmits a different one of the finite time sequences of time-multiplexed multiview images. The projection optics projects the images through the spatial light modulator onto the image projection screen, where the spatial light modulator is imaged to make a single viewing zone.
