  • Acoustography dynamic range extending device and method
    Patent number: 8255180
    Abstract: The acoustographic dynamic range extending device and method determines thresholds to reach a preset brightness with a test part and without a test part and transforms these thresholds to image data, where the thresholds can be time thresholds obtained with a single driving voltage and can be voltage thresholds obtained with an increasing driving voltage.

  • Optical imager for birefringent detector acoustic imaging systems
    Patent number: 6049411
    Abstract: Light from a collimated light source which is incident on a birefringent detector at a predetermined optimum angle interacts with the birefringent detector and is viewed by an imaging transducer in order to produce an image which shows changes in the birefringence of the birefringent detector caused by acoustic energy which has interacted with an object, the image thus showing heterogeneities in the object.
