  • Patent number: 10359513
    Abstract: A coded aperture sensing system includes a tunable coding aperture positioned relative to one or more electromagnetic (EM) detectors and voxels to scatter EM radiation traveling from the voxels towards the EM detectors. The system also includes a controller configured to determine EM fields at each of the voxels. A method includes determining a desired aggregate coding matrix of the tunable coding aperture, determining control parameters corresponding to the desired aggregate coding matrix, applying sequentially each of the control parameters to tunable inputs of the tunable coding aperture, and determining the EM fields at each of the voxels. Determining the EM fields includes determining the EM fields at least in part as a function of EM fields detected at the EM detectors responsive to each of the controls being applied to the tunable inputs of the tunable coding aperture.

  • Patent number: 10254419
    Abstract: A method of investigating a specimen using a tomographic imaging apparatus using a stage for producing relative motion of a source with respect to a specimen, so as to allow the source and a detector to image the specimen along a series of different viewing axes and a processing apparatus for assembling a tomographic image of at least part of the specimen. The investigation is carried out by considering a virtual reference surface that surrounds the specimen and is substantially centered thereon, considering an incoming point of intersection of each of said viewing axes with this reference surface, thereby generating a set of such intersection points corresponding to the series of viewing axes, choosing discrete viewing axes in the series so as to cause the set to comprise a two-dimensional lattice of points located areally on the reference surface in a substantially uniform distribution.

  • Patent number: 8904873
    Abstract: Computers with proper programs generate signals in phased array sequence. In pulsers with delays, signals are fed through a multiplexor into multiple water wedges that are attached to a valve being tested. For a sequential operation of the valves from the open to the closed position, ultrasonic signals are transmitted through fluid contained in the valve and reflected back through piezo-electric crystals to the multiplexor. By summation and merger of the signals, an image can be developed of the operation of the valve to determine if the valve is operating properly. By using multiple water wedges and pass visualization software, the operator can see exactly how the valve is functioning, which information can be stored for inspections or maintenance.

The controller establishes the annular areas 421 to 42p the number of which is larger than the number of signal lines, along line intersections between wave surfaces 51 to 54 of reflective waves and a multi-dimensional surface of the probe 1. The controller selects multiple annular areas (0, 0), (0, 1), and (0, 2) with focal depths differing, for example, by an integral multiple of the ultrasonic wavelength ?, out of the multiple annular areas being established, and connects the multiple transducer elements positioned within the selected multiple annular areas with an identical signal line.

  • Patent number: 7934425
    Abstract: A method for inspecting a part by a non-destructive ultrasound inspection, the part is immersed in an acoustic wave conducting medium and an incident ultrasound wave having a wide beam of section ? is emitted into the ultrasound-conducting medium towards the part. The characteristics of the waves reflected by faces of the part to be inspected are measured on at least a small section ?, the characteristic dimensions of which are substantially less than those of the section ?. The location of the section or sections ? is determined such that, despite the possible variations of the position of the part and the relative slopes of its faces, the section ? is always located in the volumes passed through by the reflected waves, for example substantially in an area close to the axis of the incident beam when the incident beam is controlled to be oriented substantially in a direction perpendicular to a face of the part.

  • Patent number: 7887486
    Abstract: Adaptive grating lobe suppression is provided. Received ultrasound data is measured, compared or otherwise processed to determine the presence of grating lobe energy. A further process is then altered as a function of the level of grating lobe energy. In one embodiment, the adaptive grating lobe suppression is implemented in the receive beamformer. Data representing a virtual element is formed as a normalized sum of data from adjacent sparse elements. The data from the adjacent elements is correlated to determine the presence of grating lobe energy as a function of the amount of shift associated with the peak correlation. A phase shift is applied to the data representing the virtual element where sufficient grating lobe energy is determined. In another embodiment, an amount of grating lobe energy is measured by comparing data from prior to a filter with filtered data. The filter is selected to isolate main lobe energy from grating lobe energy.

  • Publication number: 20110000299
    Abstract: There is provided an ultrasonic inspection apparatus which detects various deviations with respect to an ideal scanning position and achieves, with high accuracy, an ultrasound flaw inspection by autonomously adjusting the deviations. The ultrasonic inspection apparatus according to the present invention is provided with an integrated type ultrasound transducer including an ultrasonic transducer, an integral type ultrasound transducer control unit, an actuator for distance adjustment, an actuator for tilt control, and a distance measuring sensor. The integrated type ultrasound transducer calculates a deviation between a scanning position based on a preliminarily generated scanning path information and an ideal scanning position, and performs a deviation correction processing by autonomously controlling a distance and a tilt between an opening surface of the ultrasound transducer and an inspection region of an object to be inspected in accordance with this deviation.
