Abstract
Inspection systems provided herein may include a drive coil capable of being excited to generate a substantially uniform magnetic field about an object. The object includes a ferromagnetic adhesive adhered thereto. The inspection systems may also include an array of sensor coils adapted to detect the magnetic field from the drive coil after the magnetic field interacts with the ferromagnetic adhesive and to produce a voltage output corresponding to the detected magnetic field.
Claims20
An inspection system, comprising:
- a drive coil configured to be excited to generate a substantially uniform magnetic field about an object, wherein the object comprises a ferromagnetic adhesive adhered thereto;
- and
- an array of sensor coils configured to detect the magnetic field from the drive coil after the magnetic field interacts with the ferromagnetic adhesive and to produce a voltage output corresponding to the detected magnetic field.
An inspection system, comprising:
- a plurality of drive coils each configured to generate a substantially uniform magnetic field through an object;
- and
- a plurality of sensor coils each configured to detect the magnetic field from a drive coil of the plurality of drive coils after the magnetic field interacts with the object and to produce a voltage output corresponding to the detected magnetic field, wherein the magnetic field generated by each drive coil of the plurality of drive coils is configured to be sensed only by an associated sensor coil of the plurality of sensor coils.
An inspection system, comprising:
- a plurality of drive coils, wherein each drive coil of the plurality of drive coils is configured to generate a substantially uniform magnetic field through an object;
- and
- a sensor coil array comprising at least two subarrays of sensor coils, wherein each subarray of sensor coils is dedicated to a single drive coil of the plurality of drive coils and is configured to detect the magnetic field generated by the dedicated drive coil of the plurality of drive coils after the magnetic field interacts with the object.
