Visualizing Material Defects: Real-Time Magnetic Field Imaging with Quantum Technology

Описание: This video demonstrates the capabilities of our quantum magnetic field camera in the non-destructive inspection of ferromagnetic materials. An artificial sample—an iron plate with various drilled holes—shows how the camera can instantly and precisely visualize disruptions in magnetic flux caused by defects such as cavities, cracks, or inclusions.
Thanks to full-field, real-time imaging, even small or hidden defects that alter the local magnetic environment become directly visible as changes in magnetic field patterns. This approach enables fast, automated quality assurance and research on material behavior under dynamic conditions.

Key Applications of High-Resolution Magnetic Field Cameras

Non-Destructive Testing (NDT):
Detect cracks, inclusions, weld issues, and inhomogeneities in metals and composites without damaging the part. Used in aerospace, automotive, and rail industries for safety-critical components.

Inline Quality Control:
Monitor materials and assemblies during production. Inspect electric motors, batteries, and electronic circuit boards for shorts, current distribution, or hidden faults in real time.

Magnetic Imaging for R&D:
Characterize new magnetic materials, study magnetization processes, and visualize current flows in scientific research.

Electronics Failure Analysis:
Locate shorts, opens, and leakages in printed circuit boards, semiconductors, and 3D IC packages via magnetic imaging of the defect area.

Biomedical and Security Applications:
Sensitive mapping of magnetic biomaterials or detection of tampering in security devices.

Geoscience and Navigation:
Mapping magnetic anomalies for geology, mineral exploration, or GPS-independent navigation.
