Abstract: A method for high resolution photoacoustic imaging in scattering media using structured illumination may include illuminating a sample of an absorption object with structured illumination, including illuminating the sample with multiple different speckle patterns at different times. The method may also include detecting multiple photoacoustic signals generated by the absorption object in response to illumination with the different speckle patterns to generate multiple photoacoustic responses. The method may also include reconstructing an absorber distribution of the absorption object by exploiting joint sparsity of sound sources in the plurality of photoacoustic responses.

Abstract: Embodiments of the present invention provide a system and method for accurate, field-ready, non-destructive, and three-dimensional plant root characterization using acoustic signals. The system is portable, fast, precise, and can be used in field conditions, including moist soil, to visualize root structure or mass distribution, without damaging growing crops. The system may also be applied to characterize other underground objects, such as pipes, building foundations, archaeological artifacts, or mineral ores. During operation, the system generates a source acoustic signal. The system sends the source acoustic signal to an actuator acoustically coupled directly to a plant. The system obtains a response acoustic signal from an underground transducer monitoring a root of the plant. The system analyzes the response acoustic signal according to a model and based on the source acoustic signal. The system then determines, based on the analyzed response acoustic signal, a physical configuration of the plant root.

Abstract: Determining a modal amplitude of an inhomogeneous field includes: preparing an initial entangled state of a quantum sensor; subjecting the quantum sensor to the inhomogeneous field of the analyte; subjecting a first qudit sensor of the quantum sensor to a first perturbation pulse; receiving the first perturbation pulse by the first qudit sensor to prepare a first intermediate entangled state of the quantum sensor, the first intermediate entangled state comprising a first intermediate linear superposition; changing the initial linear superposition to the first intermediate linear superposition in response to receiving the first perturbation pulse by the quantum sensor; and determining a final entangled state of the quantum sensor after applying the first perturbation pulse to determine the modal amplitude of the inhomogeneous field of the analyte.

Abstract: A defect monitoring system has ultrasound transmitters and receivers on a wall of a structure under test such as a pipeline. The receivers are arranged in an array of locations that substantially encloses an area under test on a wall of a structure under test. The array may comprise two circumferential rings along a pipeline at different axial positions. The array of ultrasound receivers is used to measure signals that result ultrasound that leave the area through the wall for other parts of the wall. From the measured signals backward propagated signals are computed for a location within the enclosed area, compensated for a modelled effect of propagation from the location within the area to the locations of the receivers at the perimeter. The backward propagated signals for the location in the enclosed area are summed over the locations of the receivers to obtain an approximate integral over the perimeter of the area. The integral is used as a normalization factor for the backward propagated signals for the location within the area. In this way reflection and/or transmission coefficients are obtained that are indicative of the size of defects in the wall, independent of calibration of ultrasound coupling coefficients.

Abstract: The ultrasonic inspectability of a supplied part out of which a final component is to be machined is determined by following a set of inspection rules for ultrasonic inspection of the supplied part. The rules determine which parts of the polygon cannot be inspected by a scan at a given ultrasound beam angle (typical beam angles are 0°, +20° and −20° relative to the perpendicular direction to the edge) along a given edge of the polygon.

Abstract: A method and device for estimating a density value ρm indicative of a true density ρ or for estimating a viscosity value ηm indicative of a true viscosity η of a fluid is disclosed. For this, a first resonance frequency fR of a first mechanical oscillator in a reference volume and a second resonance frequency fF of a second mechanical oscillator in contact with the fluid are measured. The estimated value ρm or ηm is then derived using these resonance frequencies fR and fF. During this derivation, at least one fluid-temperature- or fluid-pressure-dependent parameter of the fluid is used. Additionally or alternatively, the first (i.e. reference) mechanical oscillator is arranged in contact with a reference fluid. Thus, fundamental errors in the derivation of the estimated value ρm or ηm are reduced and the estimated value becomes more reliable.
