摘要： Magnetic field sensor probes are disclosed which comprise primary or drive windings having a plurality of current carrying segments. The relative magnitude and direction of current in each segment are adjusted so that the resulting interrogating magnetic field follows a desired spatial distribution. By changing the current in each segment, more than one spatial distribution for the magnetic field can be imposed within the same sensor footprint. Example envelopes for the current distributions approximate a sinusoid in Cartesian coordinates or a first-order Bessel function in polar coordinates. One or more sensing elements are used to determine the response of a test material to the magnetic field. These sense elements can be configured into linear or circumferential arrays.

摘要： Precomputed databases of sensor responses are used to convert measurement data into properties of interest, for example, conductivity or lift-off. These databases of responses may be generated prior to data acquisition and provide sensor response values that span appropriate ranges for the property values. After data acquisition, estimates for the property values are obtained from measurement values by minimizing the difference between the database of responses and the measurement values. The minimization can take the form of a least-squares minimization. Alternatively, iterative techniques can be used to minimize the difference between the database and measurement values.

摘要： A method is provided for performing inverse interpolation that estimates the values of at least two identified parameters. Initially, a database of sensor responses is generated over a range of values for each of the identified parameters. The sensor responses associated with incremental changes in each parameter value form a grid cell. Each corner of a grid cell is a grid point which represents the sensor response for a specific value of each of the identified parameters. A target point of sensor values is obtained from a sensor. The database is searched to identify the grid cell which contains the target point. Using the grid cell corners as reference values, the final estimate of the parameter values is interpolated. In some cases there are three or more parameters to be estimated. The database may include sensor responses computed at multiple excitation frequencies.
