  • Corrosion monitoring
    Patent number: 9026376
    Abstract: A method of modelling a surface of an object by using ultrasonic waves transmitted along the surface comprises the steps of: transmitting the ultrasonic waves along paths along the surface, and determining travel times of the ultrasonic waves along the paths. At least some of the ultrasonic waves exhibit an S0 mode and have a frequency-dependent velocity. This velocity (c) is relatively high for frequencies up to a first bending point (BP1), decreasing relatively rapidly for frequencies between the first bending point (BP1) and a second bending point (BP2), and relatively low for frequencies beyond the second bending point (BP2). The ultrasonic waves have a frequency range which lies at or below the first bending point (BP1).

  • Ultrasonic modelling
    Patent number: 8639488
    Abstract: A method of producing a temperature model of a surface of an object using ultrasonic transducers comprises the steps of iteratively adjusting a temperature model by using measured travel times of ultrasonic waves and their predictions model-based. The ultrasonic waves used for producing the temperature model are preferably substantially non-dispersive ultrasonic waves. The method may further involve a height model of the surface, which height model is produced using substantially dispersive ultrasonic waves and is corrected by using the temperature model.
