Multiplexed wavefront sensing with a thin diffuser
Tengfei Wu, Marc Guillon, Gilles Tessier +1
In astronomy or biological imaging, refractive index inhomogeneities of e.g. atmosphere or tissues induce optical aberrations which degrade the desired information hidden behind th…
Single-shot Digital Optical Fluorescence Phase Conjugation Through Forward Multiply Scattering Samples
Tengfei Wu, Yixuan Zhang, Baptiste Blochet +3
Aberrations and multiple scattering in biological tissues critically distort light beams into highly complex speckle patterns. In this regard, digital optical phase conjugation (DO…
Chromato-axial memory effect in step index multimode fibers
Louisiane Devaud, Marc Guillon, Ivan Gusachenko +1
Multimode fibers (MMF) are used in many applications from telecomunications to minimally invasive micro-endoscopic imaging. However, the numerous modes and their coupling make ligh…
Reference-less complex wavefields characterization with a high-resolution wavefront sensor
Tengfei Wu, Pascal Berto, Marc Guillon
Wavefront sensing is a widely-used non-interferometric, single-shot, and quantitative technique providing the spatial-phase of a beam. The phase is obtained by integrating the meas…
Focusing large spectral bandwidths through scattering media
Arturo G. Vesga, Matthias Hofer, Naveen Kumar Balla +3
Wavefront shaping is a powerful method to refocus light through a scattering medium. Its application to large spectral bandwidths or multiple wavelengths refocusing for nonlinear b…
Topological transformations of speckles
Jerome Gateau, Ferdinand Claude, Gilles Tessier +1
Deterministic control of coherent random light is highly important for information transmission through complex media. However, only a few simple speckle transformations can be ach…
