Abstract

Laser speckle contrast imaging (LSCI) is a simple and quite powerful method for visualization of flow, microcirculation
and perfusion. In current study the speckle contrast variations towards breaking ergodicity conditions are considered with
a final aim of envision a practical approach allowing real-time imaging of variations in dynamic properties of complex
fluids with an opportunity of quantitative interpretation of the obtained flowing map. As example of systems with static
to dynamic transition, melting of Intralipid samples were studied. Also, investigation of influence of static layer
thickness above the dynamic sample on the ergodicity condition has been studied.
