  • Holographic acoustic imaging systems and devices based on a dynamic aperture and methods of use
    Patent number: 11467536
    Abstract: Systems and methods for generating a controlled sound field. In one example, the system and method perform or include receiving a sound wave emitted from a sound source; determining, with an electronic processor, a pattern of at least one of an amplitude change and a phase change necessary to create a desired sound field using the sound wave; determining, with the electronic processor, a plurality of passive sound-modulating elements needed to generate the pattern of at least one of the amplitude change and the phase change; and constructing the plurality of sound-modulating elements to generate the controlled sound field.
    Type: Grant
    Filed: August 24, 2017
    Date of Patent: October 11, 2022
    Assignee: Duke University
    Inventors: Yangbo Xie, Steven Cummer
  • ACOUSTIC IMAGING SYSTEMS HAVING SOUND FORMING LENSES AND SOUND AMPLITUDE DETECTORS AND ASSOCIATED METHODS
    Publication number: 20210026219
    Abstract: Acoustic imaging systems having sound forming lenses and sound amplitude detectors and associated methods are disclosed herein. According to an aspect, an acoustic imaging system includes a sound forming lens configured to focus sound waves received from a plurality of directions onto respective predetermined areas. The acoustic imaging system also includes sound amplitude detectors positioned to receive the focused sound waves at the predetermined areas and to output signals indicative of the directions of receipt of the sound waves by the sound forming lens.
