Patent number: 9995725Abstract: Disclosed herein is an apparatus including a structure containing a multiphase fluid and having a transparent window. A collimated light source emits light through the transparent window structure at a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the structure and out through the transparent window structure to impinge upon the photodetector. The photodetector has an actual dynamic range for light detection. Processing circuitry adjusts a power of the collimated light source in a series of steps dependent upon a relationship between an output level of the photodetector and a threshold to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range. Properties of the multiphase fluid are determined as a function of the measured emitted light.Type: GrantFiled: June 28, 2016Date of Patent: June 12, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Arifin Arifin, Cheng-Gang Xie

Patent number: 9885563Abstract: Dynamic digital fringe projection (DDFP) techniques for measuring warpage. The DDFP technique generates a dynamic fringe pattern, in which a proper fringe intensity distribution is dynamically determined based on the surface reflectance of an unpainted sample in order to obtain better fringe image contrasts. The DDFP technique includes the automatic segmentation method to segment the chip package and PWB regions in an unpainted PWB assembly PWBA image. It also includes calibration methods to compensate the mismatches in coordinates and intensities between the projected and captured images.Type: GrantFiled: October 10, 2014Date of Patent: February 6, 2018Assignee: Georgia Tech Research CorporationInventors: Ifeanyi Charles Ume, Sungbum Kang

Patent number: 9870610Abstract: A radiation imaging system includes a radiation imaging device, a reconstruction unit and a detection unit. The reconstruction unit generates at least two of a differential phase image, an absorption image and a small-angle scattering image based on periodic pattern images of a subject obtained by the imaging device. The detection unit performs regression analysis on at least two images of (a) the differential phase image, a differential absorption image of the absorption image and a differential small-angle scattering image of the small-angle scattering image or (b) a phase image of the differential phase image, the absorption image and the small-angle scattering image; calculates a value of an indicator indicating a relationship between the at least two images; and detects image quality deterioration due to change in relative position of the imaging device and the subject based on the value.Type: GrantFiled: June 24, 2016Date of Patent: January 16, 2018Assignee: KONICA MINOLTA, INC.Inventor: Chiho Makifuchi

Patent number: 9807359Abstract: A system and method for advanced lens geometry fitting is provided for projecting images using a projector with a non-planar lens. An initial estimate of intrinsic parameters of the projector can be determined, for example from a list; an initial estimate of extrinsic parameters of the projector can be determined based on the initial estimate of intrinsic parameters. The intrinsic parameters and extrinsic parameters can be optimized together by starting with a simple lens model and iteratively adding nonlinear terms, an error function evaluated at each iteration, for example for each set of intrinsic parameters in the list and the corresponding extrinsic parameters. As the values of the error function converges the optimized intrinsic parameters and the optimized extrinsic parameters can be used to generate images that are projected by the projector.Type: GrantFiled: January 18, 2017Date of Patent: October 31, 2017Assignee: CHRISTIE DIGITAL SYSTEMS USA, INC.Inventors: Kevin Moule, Eliezer Azi Ben-Lavi, Derek Scott, Daniel Thomson Urquhart

Patent number: 9791267Abstract: Embodiments of a shape measurement system and related methods are disclosed. In some embodiments, the system places a two-dimensional initial pattern, which can be implemented as a standalone molding or can be attached to a light source or printed on an outfit, onto a surface of a three-dimensional object. The system captures a transformed version of the initial pattern in two dimensions that is distorted due to the varying depth of the surface. The system then analyzes the transformed pattern and derives three-dimensional information regarding the target object. The analysis, which can incorporate a calibration process, can rely on the projection nature of the light source, the isomorphism/non-isomorphism of the initial pattern, and other factors.Type: GrantFiled: May 12, 2015Date of Patent: October 17, 2017Inventors: Robert Bismuth, William D. Orner, Jacob Rapoport, Amit Rohatgi

Patent number: 9752994Abstract: A measurement target is captured using two types of illumination patterns set such that only color features of specular objects change, the two images that are obtained are compared, and objects are identified as being specular objects or diffuse objects depending on whether the color features change markedly. At this time, the emission intensity distribution of each illumination pattern is devised such that specular lobe components that are included in reflected light are canceled out.Type: GrantFiled: September 3, 2014Date of Patent: September 5, 2017Assignee: OMRON CorporationInventors: Takeshi Kojima, Yasumoto Mori, Yasuhiro Ohnishi

Patent number: 9714829Abstract: An information processing apparatus includes an irradiation unit to irradiate a measurement target with a measurement pattern for distance measurement. An imaging unit obtains a captured image including the irradiated measurement target. A first detection unit detects first and second regions from the captured image. The first region includes a first portion of the measurement target that reflects a greater amount of light toward the imaging unit. The second region includes a second portion of the measurement target that reflects a lesser amount of light toward the imaging unit. A second detection unit detects, from the measurement pattern, a first region with which the first portion is irradiated and a second region with which the second portion is irradiated. A generation unit generates a measurement pattern that has different amounts of irradiation light depending on regions. A distance to the measurement target is derived using an obtained captured image.Type: GrantFiled: June 20, 2014Date of Patent: July 25, 2017Assignee: CANON KABUSHIKI KAISHAInventors: Akira Ohno, Takahisa Yamamoto, Masakazu Matsugu
