  • Patent number: 10359692
    Abstract: A laser illumination system and a method for eliminating laser speckles thereof are revealed. The laser illumination system includes laser module emitting a laser beam, a scanning unit for scanning the laser beam to form scanning beams, and a diffractive optical element which the scanning beams are passed through to form illuminating beams that are projected to an area to be illuminated or an object. Thus an image detecting unit can capture an image of the area or the object. The scanning beams are converted into the illuminating beams by the diffractive optical element that causes changes in spatial phase redistribution or light energy distribution thereof. One point in the area or on the object shows energy of partial light of at least two of the laser beams. Thus a laser speckle of the image can be eliminated by the superposition of the energy of the partial light.

  • Patent number: 10166717
    Abstract: A photo-sodification modeling apparatus is provided. The apparatus comprises: a container, a holding plate, a lifting mechanism, a light source module, and a control unit. The container provides an accommodation space for accommodating a light-curable material, and includes: a base plate and a wall structure. The base plate is transparent or translucent. The wall structure is disposed around the base plate. The lifting mechanism is used for moving the holding plate. The light source module is disposed under the container. During formation of a solidified layer of a three-dimensional object, the base plate provides an electric or magnetic field so that the light-curable material in the container will not solidify on a surface of the base plate, thus resulting in the solidified layer having a reduced viscosity when the solidified layer is closer to the surface of the base plate.
