Laser speckle contrast imaging in biomedical optics [PDF]
Journal of Biomedical Optics, 2010 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 attention, in part due to its rapid adoption for blood flow studies in the brain. We review the underlying physics of speckle contrast imaging and discuss recent developments

Synchronized renal blood flow dynamics mapped with wavelet analysis of laser speckle flowmetry data. [PDF]
PLoS ONE, 2014 Full-field laser speckle microscopy provides real-time imaging of superficial blood flow rate. Here we apply continuous wavelet transform to time series of speckle-estimated blood flow from each pixel of the images to map synchronous patterns in ...

Light-Sheet Laser Speckle Imaging
, 2022 Abstract Laser speckle imaging (LSI) as a label-free flow mapping technique has numerous potential clinical applications and plays an increasingly important role in translational medicine. Conventional LSI, however, is limited to qualitative flow change assessment and two-dimensional topographic imaging.

A narrow-band speckle-free light source via random Raman lasing
, 2015 Currently, no light source exists which is both narrow-band and speckle-free with sufficient brightness for full-field imaging applications. Light emitting diodes (LEDs) are excellent spatially incoherent sources, but are tens of nanometers broad. Lasers
