Digital holography (DH) has emerged as one of the most effective coherent imaging
technologies. The technological developments of digital sensors and optical elements have …

In recent years, the ultrasound imaging plays a major role in the medical field. It is the
diagnostic imaging technique in which the diagnosis has become more complex due to the …

One of the main drawbacks of Digital Holography (DH) is the coherent nature of the light
source, which severely corrupts the quality of holographic reconstructions. Although …

Holo-tomographic microscopy (HTM) is a label-free microscopy method reporting the fine
changes of a cell's refractive indices (RIs) in three dimensions at high spatial and temporal …

We demonstrate the effectiveness of the nonlocal means (NLM) filter for speckle denoising
in digital holography. The speckle noise adapted version of the NLM filter is compared with …

The ability to see behind flames is a key challenge for the industrial field and particularly for
the safety field. Development of new technologies to detect live people through smoke and …

In this paper, we propose a new algorithm based on deep learning to reduce the speckle
noise for coherent imaging without clean data. By learning the common information, namely …

A metasurface hologram combines fine spatial resolution and large viewing angles with a
planar form factor and compact size. However, it suffers coherent artifacts originating from …

Digital holography, recognized for its noncontact nature and high precision in three-
dimensional imaging, is effectively employed to measure the morphology of bubbles and …

We examine some fundamental theoretical limits on the ability of practical digital holography
(DH) systems to resolve detail in an image. Unlike conventional diffraction-limited imaging …
