摘要： An illumination system designed to remove laser speckle and a projection system including the same. The illumination system includes a laser light source having at least one laser, a diffractive optical element to divide a laser beam emitted from the laser light source into a plurality of sub-beams and to periodically move in such a way as to temporally average the speckle of the laser beam, and an optical fiber bundle including a plurality of fibers with the same length to divide the sub-beams into smaller sub-beams. The illumination system divides the laser beam emitted from the laser light source into sub-beams and temporally or spatially averages the sub-beams, thereby effectively reducing or removing laser speckle. The projection system employing the illumination system can provide improved image quality.

摘要： A color filter unit and a projection system employing the same. The color filter unit includes a first color selection polarization conversion element, which converts a polarization direction of a beam in a specific color band of an incident light, and a color filter, which separates light passed through the first color selection polarization conversion element according to color, so that color mixture in spectral boundaries between color beams is prevented. Because the color mixture occurring when beams into which light emitted from a white light source is separated are combined is prevented, the quality of an image is improved.
