  • Patent number: 10334359
    Abstract: Optical microphone, laser-based microphone, and laser microphone having reduced-noise components of low-noise components. A laser microphone comprises a laser-diode associated with a low-noise laser driver TX; and a photo-diode associated with a low-noise photo-diode receiver RX. The low-noise laser driver TX supplies a drive current which is a combination of a Direct Current component having a first bandwidth, and an attenuated version of an Alternating Current component having a second, different, bandwidth. Additionally or alternatively, the low-noise photo-diode receiver RX utilizes hardware-based demodulation of the analog signal, and operates to remove a Direct Current component of its output signal prior to digitization.

  • Patent number: 8960005
    Abstract: Frequency-steerable acoustic transducers (FSATs) that allow directional generation or sensing of waves propagating in two-dimensional domains. Directionality is the result of the spatial filtering effect produced by the characteristic shape of the sensing surface. A wavenumber spiral FSAT (WS-FSAT) maps the direction of wave sensing in the [0°, 180°] range to a specific frequency component in the spectrum of the received signal. The use of a wavenumber spiral FSAT operating in sensing mode can be used for the localization of broadband acoustic events. One configuration includes a broadband source generating guided elastic waves in an isotropic plate. The WS-FSAT records the plate response and defines the source location through a time-frequency analysis of the received signal. The frequency selective response of the WS-FSAT directly maps the dominant component of the received signal to the direction of arrival of the incoming wave, thus greatly facilitating the source localization procedure.

  • Patent number: 8342028
    Abstract: Disclosed is a photoacoustic measurement apparatus that irradiates a light beam onto a subject, from a same side as that of an acoustic wave detector, and that measures photoacoustic waves. The photoacoustic measurement apparatus has: an acoustic wave detector; a diffraction grating member provided in front of a detection surface of the detector; a light source that generates a light beam; and an optical system that guides the light beam from the light source towards the diffraction grating member. The diffraction grating member is configured such that the light beam led to the diffraction grating member is outputted by the diffraction grating member towards a subject surface that opposes the detection surface of the detector. As a result, light beams can strike a biological body in a near-perpendicular angle. This affords greater illumination efficiency, and allows light of substantial light energy to be irradiated deep inside biological structures.

  • Patent number: 8316713
    Abstract: A high spatial resolution phase-sensitive technique employs a scanning near field ultrasound holography (SNFUH) methodology for imaging elastic as well as viscoelastic variations across a sample surface. SNFUH uses a near-field approach to measure time-resolved variations in ultrasonic oscillations at a sample surface. As such, it overcomes the spatial resolution limitations of conventional phase-resolved acoustic microscopy (i.e. holography) by eliminating the need for far-field acoustic lenses.

  • Patent number: 8286493
    Abstract: An apparatus and a method that achieve physical separation of sound sources by pointing directly a beam of coherent electromagnetic waves (i.e. laser). Analyzing the physical properties of a beam reflected from the vibrations generating sound source enable the reconstruction of the sound signal generated by the sound source, eliminating the noise component added to the original sound signal. In addition, the use of multiple electromagnetic waves beams or a beam that rapidly skips from one sound source to another allows the physical separation of these sound sources. Aiming each beam to a different sound source ensures the independence of the sound signals sources and therefore provides full sources separation.

  • Publication number: 20120247209
    Abstract: A method is provided that enables the identification of a region of a layered composite component that a test signal has passed through. The method comprises applying a label to the test signal as it passes through the region, such that the label applied to the test signal is indicative of the said region. The labelled signal can be identified by a sensor, even if the signal is of low strength and amongst a lot of noise, such as that caused by the multiple reflections and refractions that take place when an acoustic signal passes through a layered composite component.

  • Patent number: 8266964
    Abstract: An ultrasonic flaw detection is performed to a welded portion 2 of a pipe body 1, a defect detection threshold value is determined based on the signal intensity difference between the total area of the defects existing in the region of an ultrasonic beam on a welded surface and an artificial defect, and a quality control of the pipe body is performed based on the defect detection threshold value. An equivalent defect diameter is determined from the defect density on the welded surface of the welded portion of the pipe body in a pipe axis direction and the area of the ultrasonic beam on the welded surface based on the total area of the defects existing in the region of the ultrasonic beam, and the defect detection threshold value is determined based on the equivalent defect diameter and the signal intensity difference of the artificial defect.

  • Patent number: 8266966
    Abstract: An exploration operation, in which the transmission/reception position, at which ultrasonic waves are transmitted and received, is changed by a specified pitch distance, is performed for each of a plurality of incident angles. A nonlinear image in which echo signals acquired from harmonic waves of reflected waves are presented is generated for each incident angle. Each nonlinear image is converted into a frame conversion image in accordance with the cross-sectional shape of an exploration-target area. A signal intensity threshold for removing echo signals resulting from an orientation defect is determined in advance. Frame conversion images formed by only echo signals 41a whose signal intensity is the signal intensity threshold or more are overlapped to generate a nonlinear exploration image 35. Exploration of a welded portion 23 stably provides a nonlinear exploration image 35 in which the shape of an interface 25 of the welded portion 23 is shown accurately and clearly.
