  • Patent number: 10054676
    Abstract: Apparatus for generating accurate 3-dimensional images of objects immersed in liquids including optically opaque liquids which may also have significant sound attenuation, is described. Sound pulses are caused to impinge on the object, and the time-of-flight of the reflected sound is used to create a 3-dimensional image of the object in almost real-time. The apparatus is capable of creating images of objects immersed in fluids that are optically opaque and have high sound attenuation at resolutions less than about 1 mm. The apparatus may include a piezoelectric transducer for generating the acoustic pulses; a high-density polyethylene compound acoustic lens, a 2-dimensional segmented piezoelectric detecting array positioned behind the lens for receiving acoustic pulses reflected by the object, the electric output of which is directed to digital signal processing electronics for generating the image.

  • Patent number: 9961328
    Abstract: For determining positions and orientations of mirrors, the mirrors are illuminated with parallel light rays. A first camera is arranged in an image plane onto which an objective images the mirrors. A second camera is arranged in a focal plane of the objective, and a third camera is arranged in an intermediate plane located at distances to both the image and the focal plane. At a same point in time, a first, a second and a third picture are taken with the first, the second and the third camera, respectively. The positions and the orientations of the mirrors are determined from light spots in the first and the second picture, respectively; and which of the orientations belongs to which of the positions is determined by correlating light spots in the third picture with both the light spots in the first and in the second picture.

  • Patent number: 9952245
    Abstract: A velocity deviation measuring device includes: a laser driver that causes a semiconductor laser to oscillate; a counting portion that counts run lengths of binary signals wherein interference waveforms included in the output of a photodiode that converts the output of the semiconductor laser into an electric signal have been binarized; and a calculating portion that calculates the deviation in the surface velocity of a web from the counting result by the counting portion. The counting portion binarizes the interference waveform synchronized to a sampling clock, measures the respective run lengths of the binary signal during a reference interval and a comparison interval, creates respective frequency distributions of the run lengths for the reference interval and the comparison interval, and calculates, respectively, for the reference interval and the comparison interval, the total numbers of run lengths that are at or above a threshold value Th, from the frequency distribution.

  • Patent number: 9931040
    Abstract: Systems and methods are provided for detecting the flow of blood or other fluids in biological tissue by illuminating the biological tissue with two or more beams of coherent light and detecting responsively emitted light. A difference in wavelength, coherence length, beam divergence, or some other property of the beams of illumination causes the beams to preferentially scatter from, be absorbed by, or otherwise interact with respective elements of the biological tissue. Flow properties in one or more regions of the biological tissue (e.g., a region with which both beams of light preferentially interact, a region with which only one of the beams preferentially interacts) could be determined based on detected responsively emitted light from the biological tissue. Variations in speckle patterns over time and/or space, Doppler shifts, or some other properties of the detected light could be used to determine the flow properties.

  • Patent number: 9874580
    Abstract: Disclosed is a method and a system for determining a velocity of a relative movement between a system for determining the velocity and a fluidal medium. The method includes directing at least two light beams through at least a portion of the fluidal medium using the system such that a portion of light of each light beam is absorbed by the fluidal medium. Further, the method includes detecting first and second spectral intensity profiles of at least two light beams to detect the light absorption. The method also includes determining a difference profile associated with spectral intensity differences between a first and a second spectral intensity profile; and integrating an absolute value function of the difference profile to determine the velocity. The at least two light beams are directed such that the first and second spectral intensity profiles each have a different spectral position. The system has components that are arranged to allow operation of the above-described method.

  • Patent number: 9842404
    Abstract: An imaging method and corresponding apparatus according to an embodiment of the present invention enables measurement and visualization of fluid flow. An embodiment method includes obtaining video captured by a video camera with an imaging plane. Representations of motions in the video are correlated. A textured background of the scene can be modeled as stationary, with a refractive field translating between background and video camera. This approach offers multiple advantages over conventional fluid flow visualization, including an ability to use ordinary video equipment outside a laboratory without particle injection. Even natural backgrounds can be used, and fluid motion can be distinguished from refraction changes. Depth and three-dimensional information can be recovered using stereo video, and uncertainty methods can enhance measurement robustness where backgrounds are less textured. Example applications can include avionics and hydrocarbon leak detection.
