Publication number: 20080049285Abstract: A laser processing system is disclosed for providing a relatively small velocity of a laser beam at target location while at least one scanner scans at a relatively larger velocity. The system includes a laser source, a first scanning unit, a beam expander, a second scanning unit and focusing optics. The laser source is for providing a pulsed laser output having at least one beam with a beam dimension. The first scanning unit is for scanning the laser output in a first direction along a first axis at the target location. The beam expander is for receiving the laser output and for modifying a beam diameter of the laser output and providing a modified laser output. The second scanning unit is for scanning the modified laser output from the beam expander in a second direction along the first axis at the target location.Type: ApplicationFiled: July 26, 2007Publication date: February 28, 2008Applicant: GSI GROUP CORPORATIONInventors: Adam I.

Publication number: 20080049289Abstract: An optical deflector is disclosed which is capable of preventing unnecessary reflection by a member disposed behind a reflecting portion. The optical deflector includes a substrate portion, a reflecting portion can swing about a swinging motion axis with respect to the substrate portion, and an aperture stop portion which includes an aperture and blocks at least part of a light beam other than a light beam entering the aperture among an incident luminous flux to the optical deflector. The aperture allows passage of the incident luminous flux toward the reflecting portion and that of an emergent luminous flux reflected by the reflecting portion. At least part of an aperture rim of the aperture stop portion has a shape that makes the width of the aperture narrower from a light-beam-incoming side toward a reflecting portion side.Type: ApplicationFiled: August 10, 2007Publication date: February 28, 2008Applicant: CANON KABUSHIKI KAISHAInventors: Takashi Urakawa, Keiichiro Ishihara

Publication number: 20080049291Abstract: A Micromirror Array Lens comprises a plurality of micromirrors arranged on a flat or a curved surface to reflect incident light. Each micromirror in the Micromirror Array Lens is configured to have at least one motion. The Micromirror Array Lens forms at least one optical surface profile reproducing free surfaces by using the motions of the micromirrors. The free surface can be any two or three-dimensional continuous or discrete reflective surface. The Micromirror Array Lens having the corresponding optical surface profile provides optical focusing properties substantially identical to those of the free surface. The Micromirror Array Lens can forms various optical elements such as a variable focal length lens, a fixed focal length lens, an array of optical switches, a beam steerer, a zone plate, a shutter, an iris, a multiple focal length lens, other multi-function optical elements, and so on.Type: ApplicationFiled: October 31, 2007Publication date: February 28, 2008Applicants: STEREO DISPLAY, INC., ANGSTROM, INC.Inventors: Sang Baek, Jin Sohn, Gyoung Cho, Cheong Seo
