We introduce Dynamic Laser Speckle Imaging (DLSI) to enable the wide-field measurement of the speckle temporal intensity auto-correlation function. DLSI uses the full temporal sampling of speckle fluctuations and a comprehensive model to identify the dynamic scattering regime and obtain a quantitative image of the scatterer dynamics. It reveals errors in the traditional theory of laser Doppler flowmetry and laser speckle contrast imaging, and provides guidance on the correct model to use in cerebral blood flow imaging.
