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…
