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…

Hyperspectral wavefront sensing with a multicore fiber
Baptiste Blochet, Nathalie Lebas, Pascal Berto +2
Single-shot hyperspectral wavefront sensing is essential for applications like spatio-spectral coupling metrology in high power laser or fast material dispersion imaging. Under bro…

A Polarimetric Wavefront Imager
Baptiste Blochet, Grégoire Lelu, Miguel A. Alonso +1
Imaging both the polarization and the wavefront of a light beam is a complex task that typically demands several intensity acquisitions. Furthermore, sequential acquisition solutio…
