Self-Portrait of the Focusing Process in Speckle: III. Tailoring Complex Spatio-Temporal Focusing Laws To Overcome Reverberations in Reflection Imaging
Elsa Giraudat, Flavien Bureau, William Lambert +2
This is the third article in a series of three dealing with the exploitation of speckle for imaging purposes. In complex media, a fundamental limit is the multiple scattering pheno…
Self-Portrait of the Focusing Process in Speckle: I. Spatio-Temporal Imaging of Wave Packets in Complex Media
Elsa Giraudat, Flavien Bureau, William Lambert +2
This is the first article in a series of three dealing with the exploitation of speckle for imaging purposes. Speckle is the complex interference wave-field produced by a random di…
Physics-Based Learning of the Wave Speed Landscape in Complex Media
Baptiste Hériard-Dubreuil, Emma Brenner, Benjamin Rio +4
Wave velocity is a key parameter for imaging complex media, but in vivo measurements are typically limited to reflection geometries, where only backscattered waves from short-scale…
Detection and characterization of targets in complex media using fingerprint matrices
Arthur Le Ber, Antton Goïcoechea, Lukas M. Rachbauer +6
When waves propagate through a complex medium, they undergo several scattering events. This phenomenon is detrimental to imaging, as it causes full blurring of the image. Here we d…
Self-Portrait of the Focusing Process in Speckle: II. Gouy Phase Shift for Defocus Correction and Pixel Depth Reassignment
Flavien Bureau, Emma Brenner, Naiara Korta Martiartu +7
This is the second article in a series of three dealing with the exploitation of speckle for aberration correction and reverberation compensation in reflection imaging. When probin…
Reflection Measurement of the Scattering Mean Free Path at the Onset of Multiple Scattering
Antton Goïcoechea, Cécile Brütt, Arthur Le Ber +5
Multiple scattering of waves presents challenges for imaging complex media but offers potential for their characterization. Its onset is actually governed by the scattering mean fr…
