Flow diagram of proposed method for imaging temporal decorrelation dynamics. A) Illustration of parallelized diffuse correlation imaging (PaDI) measurement strategy. Scattered coherent light from source to multiple detector fibers travels through decorrelating scattering media along unique banana‐shaped paths. Fully developed speckle on the tissue surface rapidly fluctuates as a function of deep‐tissue movement. Green dashed box marks deep‐tissue dynamics areas of interest for imaging. B) Computed autocorrelation curves from time‐resolved measurements of surface speckle at different tissue surface locations. C) Autocorrelation variations caused by deep‐tissue dynamics are computationally mapped into spatially resolved images of transient dynamics.
