Imaging depth and multiple scattering in laser speckle contrast imaging [PDF]
Journal of Biomedical Optics, 2014 Laser speckle contrast imaging (LSCI) is a powerful and simple method for full field imaging of blood flow. However, the depth dependence and the degree of multiple scattering have not been thoroughly investigated. We employ three-dimensional Monte Carlo simulations of photon propagation combined with high resolution vascular anatomy to investigate ...

Transmissive multifocal laser speckle contrast imaging through thick tissue
Journal of Innovative Optical Health Sciences, 2023 Laser speckle contrast imaging (LSCI) is a powerful tool for monitoring blood flow changes in tissue or vessels in vivo, but its applications are limited by shallow penetration depth under reflective imaging configuration.

FOCUS: Flow dynamic and optical property coupled laser speckle imaging for quantitative blood flow mapping [PDF]
APL PhotonicsLaser speckle contrast imaging (LSCI) provides label-free, wide-field blood-flow imaging with high spatiotemporal resolution, but its quantitative interpretation remains challenging because the measured speckle contrast is affected by both tissue optical

Laser speckle reduction based on angular diversity induced by Piezoelectric Benders [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 Speckle reduction techniques have been investigated in display systems with coherent light sources. We propose a simple but efficient method to reduce speckle via two fast vibrating piezoelectric benders.
