Imaging can take many forms—from optical microscopes and telescopes through
ultrasonography to X-ray tomography. However, regardless of the imaging modality, the …

Light scattering was thought to be the fundamental limitation for the depth at which optical
imaging methods can retain their resolution and sensitivity. However, it was shown that light …

Fiber-based micro-endoscopes are a critically important tool for minimally-invasive deep-
tissue imaging. However, current micro-endoscopes cannot perform three-dimensional …

A major open challenge in neuroscience is the ability to measure and perturb neural activity
in vivo from well defined neural sub-populations at cellular resolution anywhere in the brain …

Flexible fiber-optic endoscopes provide a solution for imaging at depths beyond the reach of
conventional microscopes. Current endoscopes require focusing and/or scanning …

We present a pseudo-inverse ghost imaging (PGI) technique which can dramatically
enhance the spatial transverse resolution of pseudo-thermal ghost imaging (GI). In …

Implanting fiber optical waveguides into tissue or organs for light delivery and collection is
among the most effective ways to overcome the issue of tissue turbidity, a long-standing …

A speckle pattern denotes a random granular distribution of intensity generated, eg, by light
scattered from a rough surface or transmitted through a multimode fiber. Since speckle …

We present experimental and numerical studies on principal modes in a multimode fiber
with mode coupling. By applying external stress to the fiber and gradually adjusting the …

Here, we provide experimental verification supporting the use of short-section imaging
bundles for two-photon microscopy imaging of the mouse brain. The 8 mm long bundle is …
