When it comes to “phase measurement” or “quantitative phase imaging”, many people will
automatically connect them with “laser” and “interferometry”. Indeed, conventional …

Orbital angular momentum (OAM) has the potential to dramatically enhance the amount of
information in the Internet of Underwater Things (IoUT) system. Nevertheless, underwater …

For photonic devices, structural disorder and light scattering have long been considered
annoying and detrimental features that were best avoided or minimized. This review shows …

Three-dimensional (3D) imaging has attracted more and more interest because of its
widespread applications, especially in information and life science. These techniques can …

We experimentally generate three-dimensional speckles with customized intensity statistics.
By appropriately modulating the phase front of a laser beam, the far-field speckles can …

With the success of deep learning methods in many image processing tasks, deep learning
approaches have also been introduced to the phase retrieval problem recently. These …

Wavefront sensing is an essential tool in wide research areas. However, the auxiliary
reference beam and the pixel-array detector are indispensable in most of the wavefront …

Multiple distance phase retrieval methods hold great promise for imaging and measurement
due to their less expensive and compact setup. As one of their implementations, the …

Multi-height phase retrieval by adding a thin diffuser between the object and the detector
has emerged as an effective approach for lensless imaging. However, up to 100 …

Based on a Fourier single-pixel imaging (SPI) technique and interference between an
unknown field and a reference beam, we implement amplitude and phase reconstruction of …
