Phase retrieval based on intensity-only spatiotemporal wavefront shaping
Luis Alberto Razo-López, Marc Guillon, Fabrice Lemoult +1
We introduce a phase retrieval method based on harmonic field representations generated by intensity-only spatiotemporal modulation. A periodic amplitude angular modulation encodes…
The vanishing distance: a depth-range boundary for dynamic wavefront shaping
Hugo Lassiette, Léa Testé, Léa Krafft +6
Optical imaging and transmission through scattering media conventionally rely on ballistic light, whose power decays exponentially with the optical thickness. Although ballistic li…
Nanosecond wavefront shaping to focus through agitated turbid media
Hugo Lassiette, Léa Krafft, Geoffrey Maulion +9
Multiple scattering rapidly scrambles optical fields in fog, snow and turbid water, causing op- timized wavefront corrections to become obsolete on microsecond timescales. Although…
