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…
Spectrally-resolved point-spread-function engineering using a complex medium
Antoine Boniface, Mickaël Mounaix, Baptiste Blochet +3
Propagation of an ultrashort pulse of light through strongly scattering media generates an intricate spatio-spectral speckle that can be described by means of the multi-spectral tr…
Non-invasive light focusing in scattering media using speckle variance optimization
Antoine Boniface, Baptiste Blochet, Jonathan Dong +1
Optical imaging deep inside scattering media remains a fundamental problem in bio-imaging. While wavefront shaping has been shown to allow focusing of coherent light at depth, achi…
Enhanced stability of the focus obtained by wavefront optimization in dynamical scattering media
Baptiste Blochet, Kelly Joaquina, Lisa Blum +2
Focusing scattered light using wavefront shaping provides interesting perspectives to image deep in opaque samples, as e.g. in nonlinear fluorescence microscopy. Applying these tec…
