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…
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…
Non-invasive single-shot recovery of point-spread function of a memory effect based scattering imaging system
Tengfei Wu, Jonathan Dong, Sylvain Gigan
Accessing the point-spread function (PSF) of a complex optical system is important for a variety of imaging applications. However, placing an invasive point source is often impract…
Recovering the spectral and spatial information of an object behind a scattering media
Lei Zhu, Jietao Liu, Lei Feng +3
Light passing through scattering media will be strongly scattered and diffused into complex speckle pattern, which contains almost all the spatial information and spectral informat…
Imaging through a thin scattering layer and jointly retrieving the point-spread-function using phase-diversity
Tengfei Wu, Jonathan Dong, Xiaopeng Shao +1
Recently introduced angular-memory-effect based techniques enable non-invasive imaging of objects hidden behind thin scattering layers. However, both the speckle-correlation and th…
