  • MULTIPLE LAYER INTERLAYER HAVING IMPROVED ACOUSTIC PROPERTIES
    Publication number: 20230382088
    Abstract: Multilayered interlayers having improved acoustic properties comprising a stiff skin layer(s) and a soft core layer comprising EVA are disclosed. The multilayered interlayers comprise: a first polymer layer (skin layer); a second polymer layer (skin layer); and a third polymer layer (core layer) comprising ethylene vinyl acetate resin between the first polymer layer and the second polymer layer.

  • Imaging through scattering media with high signal to noise ratio and resolution
    Patent number: 10036735
    Abstract: Systems and methods are disclosed to enhance three-dimensional photoacoustic imaging behind, through, or inside a scattering material. Some embodiments can increase the optical fluence in an ultrasound transducer focus and/or enhance the optical intensity using wavefront shaping before the scatterer. The photoacoustic signal induced by an object placed behind the scattering medium can serve as feedback to optimize the wavefront, enabling one order of magnitude enhancement of the photoacoustic amplitude. Using the enhanced optical intensity, the object can be scanned in two dimensions and/or a spot can be scanned by re-optimizing the wavefront before post-processing of the data to reconstruct the image. The temporal photoacoustic signal provides information to reconstruct the third-dimensional information.
