  • Method and apparatus for imaging with reduced level of off-axis artifacts
    Patent number: 11872084
    Abstract: An acoustic imaging system responsive to an acoustic wave emitted from an object is disclosed. The system detects a deflection angle of an electromagnetic probe beam as it passes through a coupling element. The coupling element also couples the acoustic wave emitted from the object to an acoustic detector. The probe beam deflection angle is related to an angle of propagation of the acoustic wave through the coupling element. A filtering unit is configured to remove components of the signal from the acoustic detector that are outside of a range of angles, thereby improving the angular resolution of the acoustic detector. The acoustic wave may be generated by an acoustic source, such as an ultrasound transmitter, or an electromagnetic source such as a laser.
