Quantitative phase imaging (QPI) has emerged as a valuable method for investigating cells
and tissues. QPI operates on unlabelled specimens and, as such, is complementary to …

Quantitative phase microscopies (QPMs) play a pivotal role in bio-imaging, offering unique
insights that complement fluorescence imaging. They provide essential data on mass …

Optical tweezers are tools made of light that enable contactless pushing, trap**, and
manipulation of objects, ranging from atoms to space light sails. Since the pioneering work …

In digital holography, it is crucial to extract the object distance from a hologram in order to
reconstruct its amplitude and phase. This is known as autofocusing, which is conventionally …

Recent advances in technology have allowed the production and the coherent detection of
sub-ps pulses of terahertz (THz) radiation. Therefore, the potentialities of this technique have …

In the last decades, the understanding of the complex biological mechanisms that regulate
the life and growth of single cells and their reciprocal interaction has steadily increased. In …

An in-line holographic microscope is an optical microscope outfitted with a coherent light
source, such as a laser. Light scattered by the specimen interferes with the transmitted …

Three-dimensional (3D) refractive index (RI) tomography has recently become an exciting
new tool for biological studies. However, its limitation to (1) thin samples resulting from a …

Common cameras are only sensitive to the intensity of light, discarding an essential feature
of a light wave: its phase profile or, equivalently, its wavefront profile. This Review focuses …

Many clinical procedures and biomedical research workflows rely on microscopy, including
diagnosis of cancer, genetic disorders, autoimmune diseases, infections, and quantification …
