Laser speckle imaging (LSI) techniques have emerged as a promising method for
visualizing functional blood vessels and tissue perfusion by analyzing the speckle patterns …

Real-time acquisition of human pulse signals in daily life is clinically important for
cardiovascular disease monitoring and diagnosis. Here, we propose a smart photonic …

Characterizing the orbital-angular-momentum (OAM) modes is critically important for OAM-
encoded data transfer. However, traditional characterizing approaches rely on either …

Unraveling the transport of drugs and nanocarriers in cerebrovascular networks is important
for pharmacokinetic and hemodynamic studies but is challenging due to the complexity of …

We propose a single-shot wide-field imaging method that maps local temporal intensity
decorrelations of dynamic speckle fields. Our method, named rolling shutter speckle imaging …

Throughout the central nervous system, the spinal cord plays a very important role, namely,
transmitting sensory and motor information inwardly so that it can be processed by the brain …

The laser speckle contrast imaging technique based on the dynamic light scattering theory
presents a non-scanning and wide-field method for blood flow imaging. However, its …

We introduce two-beam phase correlation spectroscopy (2B-ΦCS) as a label-free technique
to measure the dynamics of flowing particles; eg, in vitro or in vivo blood flow. 2B-ΦCS …

In microscopic imaging of biological tissues, particularly real-time visualization of neuronal
activities, rapid acquisition of volumetric images poses a prominent challenge. Typically, two …

The retina is one of the most metabolically active tissues in the body. The dysfunction of
oxygen kinetics in the retina is closely related to the disease and has important clinical …
