    • Methods and systems for detecting a plume of a first fluid in a second fluid using an acoustic wave are provided, where the first fluid has a different acoustic index of refraction than the second fluid. A horizontal array having a plurality of receiving elements receives an acoustic signal propagated through the second fluid and at least one refracted signal refracted by the first fluid. The acoustic signal and the at least one refracted signal form a received signal. An interference pattern is detected from the received signal over the plurality of receiving elements. The interference pattern is due to interference between the acoustic signal and the at least one refracted signal. A horizontal angle of refraction is determined between the acoustic signal and the at least one refracted signal from the interference pattern. The horizontal angle of refraction is indicative of a physical characteristic of the first fluid.

    • A method of modeling a surface of an object using ultrasonic transducers mounted on the surface by: providing a model of the surface comprising a primary set of surface points indicative of the height of the surface, transmitting pulsed waves from a first transducer to one or more second transducers along respective paths along the surface, measuring travel times of the pulsed waves along each path, calculating travel times based on the model of the surface, adjusting the model of the surface in response to any discrepancies between the measured travel times and the calculated travel times. The above steps are repeated until the discrepancies are smaller than a predetermined threshold. The step of calculating the travel times comprises interpolating the primary set of surface points in order to obtain an expanded secondary set of surface points, and the travel times are calculated using the expanded set.

    • A method of modelling a surface (3) of an object (2) using ultrasonic transducers (4, 5) mounted on the surface comprises the steps of: providing a model of the surface, the model comprising a primary set of surface points indicative of the height of the surface, transmitting pulsed waves from a first transducer (4) to one or more second transducers (5), the first transducer and each second transducer defining a respective path along the surface, measuring travel times of the pulsed waves along each path, calculating travel times based on the model of the surface, adjusting the model of the surface in response to any discrepancies between the measured travel times and the calculated travel times, and repeating the steps of transmitting, measuring, calculating and adjusting until the discrepancies are smaller than a predetermined threshold. The step of calculating the travel times comprises the sub-step of interpolating the primary set of surface points in order to obtain an expanded secondary set of surface points, the travel times being calculated using the expanded set. Thus the number of surface points to be determined is substantially reduced.
