Laser speckle contrast imaging in biomedical optics
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 …

Review of laser speckle contrast techniques for visualizing tissue perfusion
When a diffuse object is illuminated with coherent laser light, the backscattered light will form
an interference pattern on the detector. This pattern of bright and dark areas is called a …

Dynamic light scattering imaging
We introduce dynamic light scattering imaging (DLSI) to enable the wide-field measurement
of the speckle temporal intensity autocorrelation function. DLSI uses the full temporal …

Detrimental effects of speckle-pixel size matching in laser speckle contrast imaging
Through a series of simulations and experiments, we demonstrate that the frequently cited
criterion of matching speckle size to detector element (pixel) size in laser speckle contrast …

Laser speckle imaging to monitor microvascular blood flow: a review
Laser speckle is a complex interference phenomenon that can easily be understood, in
concept, but is difficult to predict mathematically, because it is a stochastic process. The use …

Review of laser speckle-based analysis in medical imaging
Speckle pattern forms when a rough object is illuminated with coherent light (laser) and the
backscattered radiation is imaged on a screen. The pattern changes over time due to …

Intraoperative laser speckle contrast imaging for real-time visualization of cerebral blood flow in cerebrovascular surgery: results from pre-clinical studies
A Mangraviti, F Volpin, J Cha, SI Cunningham… - Scientific reports, 2020 - nature.com
Cerebrovascular surgery can benefit from an intraoperative system that conducts continuous
monitoring of cerebral blood flow (CBF). Such a system must be handy, non-invasive, and …
