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 back from biological tissue is diffracted through the limiting aperture of focusing optics. Mobile scatterers cause the speckle pattern to blur; a model can be constructed by inversely relating the degree of blur, termed

The reflected light passing through the laser beam creates so-called „Speckle Patterns“. The image size of the CCD camera is called „Field of View“. Speckle 

Optical zoom means you can assess small areas right up to a full size adult hand with a single imager. In this work, Chen and colleagues push one neural imaging modality, based on laser speckle contrast, deep into the mouse brain using a microendoscope. They are able to insert their thin tool many millimeters into the tissue without causing much damage, and can then directly record the cerebral blood flow within brain areas such as the thalamus, which is far from the reach of traditional optics. A python script for analysis of laser speckle images for the determination of the roughness of surfaces. Running 'analysis.py' with python 2.x will grab all '.TIF' files from the current working directory and log their 'speckle contrast' (see e.g. Dunn, A. K.

Laser speckle imaging




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 de-velopments to improve the quantitative accuracy of blood flow mea-sures. We also review applications of laser speckle
