    Analysis of three-dimensional acoustic data is a very important step in object detection, especially in robotic detection. It provides rich information of object classification on the region of interest. In this study, an approach on displaying multispectral acoustic imaging (MSAI) data was proposed based on a neural network called Self-Organizing Maps (SOM), which effectively realized dimensional reduction of high-dimensional data. The multispectral acoustic imaging data was obtained from an example that a rigid surface with 9 different holes was illuminated by sound waves sweeping over the frequency range from 1 to 20 kHz with a 30 Hz step. The results showed that the profiles of the holes were identified by their colors in the reconstructed image.

  • Beamforming-Based Acoustic Imaging for Distance Retrieval

    Beamforming is one of the ultimate opportunity to improve distance systems in order to detect punctual and widespread obstacles. Distance ranging for mobile and fixed systems, namely, cars, vehicles, vessels and airplanes, is a key issue for nowadays demands. Distance between cars and from obstacles can be established and measured using laser and ultrasound. Cloudy and foggy conditions are utmost requirements for testing distance ranging facilities. If based on ultrasound, they can be easily integrated by a sophisticated on-board software in order to perform new features. This paper introduces interesting aspects of defining new requirements for an acoustic imaging capable of reconstructing obstacle features by targeting it using a special array of sensors.

The second and third systems use rectangular acoustic transducer array and linear array respectively. Both of acoustic signals acquired by the arrays are totally digitized by the related electronics and processed by the advanced DSP boards. So both imaging processes are absolutely digital. They have the advantages of easy implement, programmable, and compact, etc., so that they can meet to the variant missions of UUV (unmanned underwater vehicle).

  • Ultra-short-pulse acoustic imaging using complex-valued spatio-temporal neural-network for null-steering: Experimental results

    This paper reports experimental results of a wideband acoustic imaging method based on power-inversion adaptive array (PIAA) scheme realized by a complex- valued spatio-temporal neural network (CVSTNN). For acoustic imaging with a high resolution in the range direction (direction of propagation), used pulse should be short. A short pulse has a wide frequency band, which is also favorable for avoidance of target breaking through acoustic resonance. However, because of the wide bandwidth, conventional adaptive arrays often fail in beamforming or null steering. We combine a CVSTNN and PIAA to realize a precise null steering. Experiments demonstrate that the CVSTNN-PIAA method presents a higher resolution than conventional methods.

  • Low-cost one-bit MEMS microphone arrays for in-air acoustic imaging using FPGA's

    Recent advancements in MEMS microphone integration have led to the production of low-cost digital MEMS microphones which are suitable for applications in the ultrasonic acoustic spectrum. Using these microphones instead of their analog counterparts can greatly simplify board- and system-design and reduce overall construction cost of an array built with these sensors. In this paper we will propose an architecture for using these low-cost one-bit MEMS microphones to construct a microphone array and demonstrate their applicability in beamforming-based acoustic imaging algorithms targeted at 3D sonar sensors. We developed a small prototype array do demonstrate that these microphones are well suited for array applications, and the proposed system architecture, developed around an FPGA-SOC, is shown to be ideally suited to interface with a large number of these microphones.

  • On the design of a transversal filter bank for parallel processing multiple image lines in real-time acoustic imaging

    We present a new method for designing a transversal filter bank for parallel processing echo data in real-time active acoustic imaging. The method is based on a discretized linear spatio-temporal formulation of an imaging system which uses transmitter arrays with coded-excitation. The filter coefficients are derived from a pseudo-inverse operator which not only decouples echoes from different image lines, but also provides pulse compression along the range direction. The new method, together with the proposed coded-excitation imaging modality, may find many applications in sonar, NDE and biomedical imaging areas.

  • Feasibility study of photo thermal acoustic imaging of buried nanowires in Gate-All-Around Nanowire FETs

    With the ongoing drive to integrate more functionality and processing power on the same semiconductor area, the device structures have become 3D. Such structures, like FinFETs and their successors Gate-All-Around (GAA) nanowire FETs, bring on new challenges to measure their geometry and material properties non-destructively at the nanometer scale. Photo Thermal Acoustic Imaging (PTAI) is a potential metrology method. Here, the sample is heated locally by a pulsed optical pump beam. This generates a propagating elastic wave in the sample, which is scattered by inclusions in the sample. Part of the scattered energy travels to the sample surface, where the surface deformations are sensed by an optical probe beam using interferometric detection. Thus, no physical contact for actuation or sensing is required. Moreover, PTAI allows for metrology through optically opaque layers. This work investigates the feasibility of PTAI for the detection and imaging of nanowires. In PTAI a pulsed pump beam locally heated up a volume of the material - the absorption of optical energy and its conversion into heat were calculated analytically. The temperature distribution generated by the heat, the creation of a stress wave due to thermal expansion and the propagation and scattering of the resulting elastic waves were calculated using finite element modeling. The probe beam was modeled by spatially averaging the sample surface displacement. The datasets were imaged using a wavenumber frequency domain mapping. The simulation results showed that the detection of nanowires should be feasible using PTAI, however the imaging of nanowires is limited by the acoustic frequency and optical probe beam width.

  • Study on non contact acoustic imaging method for non destructive inspection using SLDV and LRAD

    We propose a new non-contact acoustic imaging method for nondestructive inspection using scanning laser Doppler vibrometer (SLDV) and long range acoustic device (LRAD). In this method, Surface vibration, which is generated by air borne sound, is measured using SLDV. This time, the styrofoam board (300 × 300 × 100 mm3) was buried at 50 mm depth in the concrete are used as a substitute of a cavity in the concrete. As an experimental result, a styrofoam board is clearly imaged by the vibration velocity of the concrete surface. And also, we confirmed the response range of the frequency of a buried object. Clearer image is formed by the optimum frequency response range (OFR) method.

  • Feasibility Study of Acoustic Imaging for Human Thorax Using Contrast Source Inversion

    In this paper, we study an acoustic imaging method based on contrast source inversion and its feasibility in quantitatively reconstructing the thorax compressibility and qualitatively reconstructing the thorax attenuation and density. The existence of gradient and divergence operator in the acoustic wave equation makes the relationship between the contrast and the total pressure highly nonlinear. To reduce this nonlinearity, we introduce two contrast sources to ensure the symmetry of the equation, such that the inverse problem can be solved efficiently using conjugate gradient method. Moreover, to improve the stability of the algorithm, we applied the multiplicative regularization scheme with two additive regularization factors. Numerical results show that the acoustic parameters of human thorax can be properly reconstructed at frequency of tens of kHz using this inverse algorithm.
