Experimental layout used in the measurement of flow. A syringe pump is interfaced to the microfluidic phantom through a universal interface block. On the right hand side a simple speckle flow imaging system (explained later in the paper) consisting of a fast acquisition camera, a laser source and an imaging lens.
