Particle Characterization via Doppler Distribution
Abstract
This patent application discloses systems and methods for determining information about particle geometry. As such, an ultrasonic transducer acts as both a transmitter and a receiver, The transducer insonifies a particle and scattered waves are then received by the transducer -- now acting as a receiver. A small flat target moving relative to a stationary receiver will lead to the same radiated field as waves propagating through an equivalent moving aperture. Based on the Doppler distribution of the scattered or radiated waves resulting from relative motion between the particles and a receiver, the acoustic pressure field in the plane of the equivalent two-dimensional aperture can be inferred. The equivalent aperture geometry can be obtained from the inferred field. Hence, the particle geometry can be determined.
