Spatially incoherent illumination interferometry: a PSF almost insensitive to aberrations
Peng Xiao, Mathias Fink, A. Claude Boccara
We show that with spatially incoherent illumination, the point spread function width of an imaging interferometer like that used in full-field optical coherence tomography (FFOCT)…
Spatio-Temporal Imaging of Light Transport in Highly Scattering Media under White Light Illumination
Amaury Badon, Dayan Li, Geoffroy Lerosey +3
Imaging the propagation of light in time and space is crucial in optics, notably for the study of complex media. We here demonstrate the passive measurement of time-dependent Green…
Slow waves in locally resonant metamaterials line defect waveguides
Nadège Kaina, Alexandre Causier, Yoan Bourlier +3
In the past decades, many efforts have been devoted to the temporal manipulation of waves, especially focusing on slowing down their propagation. In electromagnetism, from microwav…
Exploiting spatiotemporal degrees of freedom for far field subwavelength focusing using time reversal in fractals
Matthieu Dupré, Fabrice Lemoult, Mathias Fink +1
Materials which possess a high local density of states varying at a subwavelength scale theoretically permit to focus waves onto focal spots much smaller than the free space wavele…
