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…
Electrically Driven Varifocal Silicon Metalens
Adeel Afridi, Josep Canet-Ferrer, Laurent Philippet +3
Optical metasurfaces have shown to be a powerful approach to planar optical elements, enabling an unprecedented control over light phase and amplitude. At that stage, where wide va…
Wavefront-sensing with a thin diffuser
Pascal Berto, Hervé Rigneault, Marc Guillon
We propose and implement a broadband, compact, and low-cost wavefront sensing scheme by simply placing a thin diffuser in the close vicinity of a camera. The local wavefront gradie…
