Spectral Geometry and Dispersion-Constrained Projection of Diffusive Fields
Pengfei Zhu, Julien Lecompagnon, Philipp Daniel Hirsch +1
Diffusive fields obey operator-imposed relations between spatial structure and temporal decay, yet conventional spectral filtering selects components primarily according to frequen…
Structured Illumination Scanning Thermography (SISTER)
Pengfei Zhu, Julien Lecompagnon, Philipp Daniel Hirsch +1
Conventional non-invasive photothermal imaging techniques are fundamentally constrained by the diffusive nature of heat transport, which causes severe energy dissipation during sub…
Generalized Virtual-Wave Theory for Photothermal Coherence Tomography under Arbitrary Excitation Toward Non-Contact Industrial Inspection of Composite Materials
Pengfei Zhu, Julien Lecompagnon, Philipp Daniel Hirsch +1
Photothermal imaging is a powerful noncontact and nondestructive technique for subsurface inspection of composite materials, yet its performance is fundamentally limited by the dif…
