    摘要： Provided is a projection television TV having a digital micro mirror device (DMD) which includes micro-mirrors to reflect light from a light source according to an ‘on’ or ‘off’ state of the micro mirrors. An illuminating block provides light to the DMD in a uniform optical intensity. A projecting block projects the light reflected from the DMD onto a screen. The projection TV features a projection aperture positioned in the projecting block or the illuminating block arranged perpendicularly to an optical axis. The projection aperture forms an optical path and includes projection areas to pass the light and blocking areas to block the light. The projection area and the blocking area are formed on a cross section of the light with a predetermined space.

    摘要： A highly efficient lighting system, a scrolling unit, and a projection system adopting the highly efficient lighting system and the scrolling unit are provided. The scrolling unit has at least one lens cell. From the viewpoint of light incident upon the at least one lens cell, the rotation of the at least one lens cell is converted into a rectilinear motion of a lens array, such that incident light is scrolled. The projection system includes a light source, an optical splitter, at least one scrolling unit, and a light valve. The optical splitter splits light emitted from the light source according to wavelenght. The at least one scrolling unit has at least one lens cell. The lens cell has an incident side and an emitting side and divides incident light into light beams. The rotation of the lens cell causes a rectilinear motion of the light beams, thereby scrolling incident light. The light emitted from the light source is separated into color beams by the optical splitter and the scrolling unit, and the color beams are focused on the light valve. The light valve processes incident light according to an input image signal in order to form a color image.

    摘要： A compatible optical pickup capable of recording or reproducing information on or from compact disc (CD) family media such as CD rewritable (CD-RW) and digital versatile disc (DVD) by adopting a stepped planar lens having a plurality of gratings. The compatible optical pickup includes a first optical source for emitting a first light beam having a predetermined wavelength; a second optical source for emitting a second light beam having a long wavelength relative to the first light beam; an optical path changing element for changing the traveling path of an incident light beam; an objective lens for condensing the first and second light beams onto optical discs having different thicknesses, respectively; an optical diffraction element having a first region which directly transmits the first and second light beams incident thereto, and a second region bounding the first region, which directly transmits the incident first light beam and diffractingly transmits the second light beam toward an optical axis; and a photodetector for detecting an information signal and an error signal from the first and second light beam which have been reflected by the optical discs and passed through the optical path changing element. Also, the optical diffraction element is a stepped planar lens in which one or more stepped pattern periods each having a plurality of annular gratings are arranged in the second region, wherein the depths of the gratings become smaller moving away from the optical axis, and the maximum depth thereof is a predetermined value.

    摘要： An optical disc can increase an information storage capacity by reducing the track width of the optical disc. An optical pickup for a narrow track optical disc includes an optical shielding portion having a desired light intensity distribution with respect to a target track and the tracks adjacent to the target track on the optical disc. The optical shielding portion is disposed on the optical path between the light source and the optical disc and shields part of the light beam proceeding toward the optical disc, to provide a light intensity distribution such that only the beam spot focused on the target track is used to detect information stored in the target track. Thus, the beam spot focused on the target track of the optical disc has track crosstalk having a magnitude by which information can be read from the target track. The optical pickup can provide an excellent performance even in the case that the optical pickup is adapted in a high-definition DVD to be commercialized in the future.

    摘要翻译： 光盘可以通过减小光盘的轨道宽度来增加信息存储容量。 用于窄轨道光盘的光学拾取器包括具有相对于目标轨道的期望的光强度分布的光学屏蔽部分和与光盘上的目标轨道相邻的轨道。 光学屏蔽部分设置在光源和光盘之间的光路上，并屏蔽朝向光盘的光束的一部分，以提供仅使用聚焦在目标轨道上的光束点的光强度分布 以检测存储在目标轨道中的信息。 因此，聚焦在光盘的目标轨道上的束斑具有具有可以从目标轨道读取信息的幅度的轨道串扰。 即使在将来在高分辨率DVD中适应商业化的光学拾取器的情况下，光拾取器也能够提供优异的性能。

    摘要： An optical disc includes a substrate having micro-embossments, in which flat portions referred to as lands, and track guides, referred to as hills, and which protrude from the surfaces of the flat portions are formed. A reflective layer is formed on the substrate, a dielectric layer is formed on the reflective layer, a recording layer is formed on the dielectric layer, and a protective layer is formed on the recording layer. Thus, the lands and hills on the substrate of the optical disc enable disc fabrication to more easily facilitate manufacturing of the optical disc. Accordingly, tracks of the disc can be narrowed, to thereby enhance a recording density of the optical disc.
