Title: METHOD AND SYSTEM FOR INSPECTION OF COMPOSITE MATERIAL COMPONENTS
Abstract:
A non-destructive inspection of epoxy-based objects by creating a substantially uniform magnetic field of about 0.1 to 0.5 Tesla within a magnetic field region at least partially overlapping with a test zone where the inspected object is to be located, applying electromagnetic excitation signals in the test site to affect the nuclei magnetization in the inspected object and concurrently generating magnetic gradients in three orthogonal directions thereinside, to thereby cause spatially resolved nuclear spin echo signals from the inspected object. Data corresponding to electromagnetic radiation received responsive to the nuclear spin echo signals from the inspected object is processed to extract data indicative of the spatially resolved nuclear spin echo signals from the inspected object, and magnetic resonance images indicative of structural defects in the object are then generated using the extracted data.
