  • Patent number: 10401285
    Abstract: The present invention relates to an apparatus for measuring surface properties of a polishing pad which measures surface properties such as surface topography or surface condition of a polishing pad used for polishing a substrate such as a semiconductor wafer. The apparatus for measuring surface properties of a polishing pad includes a laser beam source configured to emit a laser beam, and a photodetector configured to detect scattered light that is reflected and scattered by the polishing pad, an optical Fourier transform being performed on the detected scattered light to produce an intensity distribution corresponding to a spatial wavelength spectrum based on surface topography of the polishing pad. The laser beam is applied to the polishing pad at such an incident angle that the laser beam does not reach a bottom portion of a pore formed in the surface of the polishing pad.

    Abstract: A rotary element is equipped with a pattern representing a reflected binary code on at least three bits. A detection circuit is configured to sense the pattern and deliver an incident signal encoded in reflected binary code on at least three bits. The incident signal is converted by a transcoding circuit into an intermediate signal encoded in reflected binary code on two bits. A decoding stage decodes the intermediate signal and outputs at least one clock signal representing the amount of rotation of the rotary element and a direction signal representing the direction of rotation. A processing circuit determines the movement of the rotary element, and has at least one general purpose timer designed to receive the at least one clock signal and direction signal.

  • Patent number: 8669507
    Abstract: A laser scanning device includes a laser output unit, a scanner, a light splitting unit, an imaging compensation unit, a detection unit, and a control unit. A scanning focusing unit included in the scanner focuses a laser beam emitted by the laser output unit to scan an object. A visible light beam received by the canning focusing unit is reflected by the light splitting unit and is incident into the imaging compensation unit. Next, the detection unit receives the visible light beam passing through the imaging compensation unit, and outputs a detection signal. The control unit adjusts the detection signal according to the wavelength of the visible light beam, the wavelength of the laser beam, the scanning focusing unit, and the imaging compensation unit. Therefore, the laser scanning device may compensate the aberration and the dispersion caused when the visible light beam passes through the scanning focusing unit.

  • Patent number: 8237103
    Abstract: A mechanical galvanometer tilt control system includes two beam detection sensors that detect vertical displacement caused by the horizontal rotation of a galvanometer and the vertical rotation of a photoconductive drum. The galvanometer may be in communication with a mirror holder that holds a mirror. The mirror holder may be operable to horizontally rotate the mirror as the mirror reflects a light beam onto a photosensitive image forming surface of the photoconductive drum. The two beam detection sensors receive the reflected light beam as the galvanometer generates one or more forward-going and one or more reverse-going scanlines on the photosensitive image forming surface. The mechanical galvanometer tilt control system may further determine an amount of vertical correction required to correct for the vertical displacement caused by the rotation of the galvanometer and the rotation of the photoconductive drum.

  • Publication number: 20120085825
    Abstract: A laser scanning system for generating a laser scanning pattern in a scanning field, while amplifying the scan-angle multiplication factor of rotating mirrors employed therein. The laser scanning system employs rotatable laser scanning assembly having an axis of rotation and first and second rotating mirrors with normal vectors that are coplanar with each other and said rotational axis, and which form an acute angle substantially less than 90 degrees so as to provide a laser scanning assembly with a scan angle multiplication factor that is greater than 2.0. A cluster of stationary mirrors mounted about the first and second rotating mirrors, for sweeping a laser beam off the cluster of stationary mirrors after a laser beam has been reflected off the first rotating mirror, then reflected off the second rotating mirror, and then directed outwardly towards an array of pattern mirrors, so as to generate a resultant laser scanning pattern within the scanning field.

  • Patent number: 8056810
    Abstract: Systems and techniques for multiple laser and multiple detector bar code scanning. multiple laser sources generate multiple laser beams directed to a rotating spinner and along optical paths to emerge from a scanner as multiple scan beams. The scan beams trace out a scan pattern within a scan volume. As the multiple scan beams strike an object within the scan volume, reflected light rays are produced representing reflections of the multiple scan beams. As the reflected light rays enter the scanner, they are directed to a collector and focused onto a plurality of detectors so that reflected light rays representing reflections of each scan beam are focused onto a detector associated with the laser source from which the scan beam originates.

  • Patent number: 7858923
    Abstract: A light beam scanning apparatus capable of forming a high contrast electrostatic latent image. A polygon mirror scans a light flux emitted from a light source in a main scanning direction. An electrostatic latent image in an irradiation position irradiated by the scanned light flux is formed onto a photosensitive drum. An electro-optic crystal structure disposed in a light path between the light source and the polygon mirror deflects a course of the light flux emitted from the light source to the main scanning direction by applying a voltage. A controller maintains the irradiation position on the photosensitive drum irradiated by the light flux, by controlling a voltage to be applied to the electro-optic crystal structure according to the scanning information during the time period in which an electrostatic latent image corresponding to one dot is formed on the photosensitive drum.
