When laser light illuminates a diffuse object, it produces a random interference effect known
as a speckle pattern. If there is movement in the object, the speckles fluctuate in intensity …

This review describes the diffusion model for light transport in tissues and the medical
applications of diffuse light. Diffuse optics is particularly useful for measurement of tissue …

First introduced in the 1980s, laser speckle contrast imaging is a powerful tool for full-field
imaging of blood flow. Recently laser speckle contrast imaging has gained increased …

This review celebrates the 30th anniversary of the first in vivo near-infrared (NIR)
spectroscopy (NIRS) publication, which was authored by Professor Frans Jöbsis. At first …

Optical brain imaging has seen 30 years of intense development, and has grown into a rich
and diverse field. In-vivo imaging using light provides unprecedented sensitivity to functional …

Laser speckle contrast imaging (LSCI) has emerged over the past decade as a powerful, yet
simple, method for imaging of blood flow dynamics in real time. The rapid adoption of LSCI …

We describe a multispeckle dynamic light scattering technique capable of resolving the
motion of scattering sites in cases that this motion changes systematically with time. The …

Diffuse correlation spectroscopy (DCS) is an emerging optical modality used to measure
cortical cerebral blood flow. This outlook presents a brief overview of the technology …

Anesthesia has broad actions that include changing neuronal excitability, vascular reactivity,
and other baseline physiologies and eventually modifies the neurovascular coupling …

Laser Speckle Contrast Imaging (LSCI) is a wide field of view, non scanning optical
technique for observing blood flow. Speckles are produced when coherent light scattered …
