    摘要: A liquid crystal projection system (70) includes a light source (50) for emitting a white light beam of three primary colors, a polarizer (51) for polarizing the white light beam, a separating mirror (52), first and second reflecting mirrors (53, 54), first and second polarization separators (56, 57), a half-wave plate (55), a color separator (58), image modulation devices (60R, 60G, 60B) and a projection lens (59). The separating mirror splits the incident polarized white light beam into two sets of polarized light beams, a monochromatic light beam and a bichromatic light beam that are respectively output to the first and second reflecting mirrors (53, 54). The polarized monochromatic light beam is reflected by the first reflecting mirror, transformed to a light beam with reversed polarization by the half-wave plate, and output to the first polarization separator. The polarized bichromatic light beam is reflected by the second reflecting mirror to the second polarization separator for polarization splitting, and then transmitted to the color separator for separating the two primary colors. The image modulation devices are arranged on sides of the first modulating the incident monochromatic and bichromatic light beams. The projection lens is disposed on one side of the second polarization separator.

    摘要: A light emitting system is disclosed, including a light generator, a complex lens and an activating unit. The light generator provides a light beam emitted in a first direction in parallel to an optic axis. The complex lens, disposed on a path of the light beam, includes a plurality of micro structures for refracting the light beam. The activating unit includes an activating member coupled to the complex lens. The activating member activates the complex lens with an activation frequency to reciprocally move in a second direction alternate to the first direction. By the disposition of the complex lens, the energy of the light beam is uniformly distributed. Additionally, speckle produced by the light beam is reciprocally moved within an area by the activating unit, creating a photogene reaction, to successfully eliminate existence of the speckle.

    摘要: An illumination module is provided in the invention. The illumination module includes a light source having a plurality of light emitting elements arranged in a linear array and a light guide device. The light guide device receives light from the light source and generates uniform light which is transmitted onto an article to be scanned, has a longitudinal direction, and includes a diffraction structure and a reflection portion. The diffraction structure has a shape inducing light to be scattered and deflects the scattered light toward the longitudinal direction. The reflection portion reflects the light scattered and deflected by the diffraction structure, and is inclined to have an inclined angle with the light propagating direction. In addition, the reflection portion is formed on the diffraction structure or apart from it.
