  • Patent number: 10845470
    Abstract: Described herein are methods and systems for protecting a light detection and ranging (LIDAR) device against external light that is originated at a light source other than a light source of the LIDAR device and that is being emitted towards the LIDAR device. In particular, the LIDAR device may be equipped with a mitigation system that includes an interference filter, an absorptive filter, an adaptive filter, and/or a spatial filter. Additionally or alternatively, the LIDAR device may be operated to carry out reactive and/or proactive mitigation operations. For example, the LIDAR device may be operated to vary over time characteristics with which light is being emitted and to only detect light having characteristics that match the characteristics with which light is being emitted. In another example, the LIDAR device may be operated to activate a shutter to block the external light from being detected by the LIDAR device.

Light emitted by the light source (1) sequentially passes through the collimator lens (2), the filter (3), the polarizer (4), the beam splitter (5) and the objective lens (7) and thereby forms a measuring light incident on the thin film. The objective lens (7) and the beam splitter (5) gather light reflected from the thin film, and the planar array detector (11) and the processor (13) measure physical parameters of the thin film based on the gathered reflected light. The device further includes a stop configured to block interfering light reflected from the transparent substrate during the measurement.

The method comprises irradiating an inspection target with light using a polarizer, receiving light that is reflected by the inspection target and passes through an analyzer by a line scan camera, synthesizing an amplitude and a phase of wavelength of the light into an intensity of light, comparing the intensity of the light with predetermined intensities of light for inspection targets having different thicknesses; and detecting a defect of the inspection target based on the compared intensity with the predetermined intensities. It can be determined whether there is a transparent film, and the thickness of the transparent film can be measured in a large area. The inspection is carried out in real-time after the transparent film is formed, such that if a defect is generated, it can be fed back immediately to thereby reduce defects.

  • Publication number: 20150108375
    Abstract: A method includes, using at least one processing device, obtaining an image of a web of creped tissue paper and identifying a caliper measurement of the web using the image. The caliper measurement is based on a dominant frequency of the web and a standard deviation of diffusely-reflected light from the web. The dominant frequency of the web can be based on a number of crepe folds having a dominant crepe fold size that fit within a specified unit distance of the web in the image. The dominant crepe fold size can be determined using a discrete auto-covariance function of the image or a second image of the web. The standard deviation can be based on a variation of reflected light from larger crepe structures in the web.

  • Patent number: 8933401
    Abstract: A scanning transmission electron microscopy (STEM) system is disclosed. The system may make use of an electron beam scanning system configured to generate a plurality of electron beam scans over substantially an entire sample, with each scan varying in electron-illumination intensity over a course of the scan. A signal acquisition system may be used for obtaining at least one of an image, a diffraction pattern, or a spectrum from the scans, the image, diffraction pattern, or spectrum representing only information from at least one of a select subplurality or linear combination of all pixel locations comprising the image. A dataset may be produced from the information. A subsystem may be used for mathematically analyzing the dataset to predict actual information that would have been produced by each pixel location of the image.

  • Patent number: 8575581
    Abstract: An apparatus includes: a body including a port into which a medium is insertable; a light source that is provided in the body and illuminates when an image is read for the medium that has been inserted into the port; a guide and output unit that is optically connected to the light source, guides light emitted from the light source, and outputs the guided light into the port; a receiver that detects the output light; and a determiner that determines whether the medium has been inserted into the port based on a result of the detection. The light source also illuminates when the determiner makes the determination. A region in the port through which the light output from the light guide and output unit passes exists from one end to the other end of the port in a width direction being a longitudinal direction of the port.

  • Patent number: 8489237
    Abstract: Methods correcting wafer position error are provided. The methods involve measuring wafer position error on a robot during transfer to an intermediate station. This measurement data is then used by a second robot to perform wafer pick moves from the intermediate station with corrections to center the wafer. Wafer position correction may be performed at only one location during the transfer process. Also provided are systems and apparatuses for transferring wafers using an intermediate station.

  • Patent number: 8461562
    Abstract: Provided is a web carrier which can prevent creasing of a web by detecting a sign of creasing of a web during carriage of the web. The web carrier (1) for carrying a sheetlike web (10) by means of a plurality of rollers (2) detects the linear pattern of a waveform generated on the web (10) from an image picked up by means of a camera (imaging means) (3) using an image analysis means (73) in a controller (7), recognizes a state becoming the sign of creasing with the aid of the image and simultaneously analyzes the entering direction of the linear pattern into a guide roller (2c), drives the shaft (20c) of the guide roller (angle adjusting roller) (2c) in the direction of canceling the waveform (so that the web is not creased), and controls an alignment adjusting means (5) such that the web is not creased.
