High spatial resolution and high contrast optical speckle imaging with FASTCAM at the ORM [PDF]

, 2010
In this paper, we present an original observational approach, which combines, for the first time, traditional speckle imaging with image post-processing to obtain in the optical domain diffraction-limited images with high contrast (1e-5) within 0.5 to 2 ...

Measuring human cerebral blood flow and brain function with fiber-based speckle contrast optical spectroscopy system

bioRxiv, 2023
Cerebral blood flow (CBF) is crucial for brain health. Speckle contrast optical spectroscopy (SCOS) is a technique that has been recently developed to measure CBF, but the use of SCOS to measure human brain function at large source-detector separations ...

Adaptive window space direction laser speckle contrast imaging to improve vascular visualization.

Biomedical Optics Express, 2023
Vascular visualization is crucial in monitoring, diagnosing, and treating vascular diseases. Laser speckle contrast imaging (LSCI) is widely used for imaging blood flow in shallow or exposed vessels.

Dynamic light scattering and laser speckle contrast imaging of the brain: theory of the spatial and temporal statistics of speckle pattern evolution

Biomedical Optics Express, 2023
Dynamic light scattering (DLS) and laser speckle contrast imaging (LSCI) are closely related techniques that exploit the statistics of speckle patterns, which can be utilized to measure cerebral blood flow (CBF).
