Abstract

We establish the equivalence between laser speckle contrast-based and diffuse correlation spectroscopy methods in in vivo imaging of blood flow using the Volterra integral equation theory. We further substantiate the need of regularized fitting while employing the multiexposure speckle contrast imaging to recover autocorrelation function.
