“…Therefore any change of one of these parameters can distort this profile. Changes in glucose level in blood affect also the viscosity of blood [ 28 ], while a change in viscosity of fluid affects the friction between the blood fluid and the vessel walls. Our assumption for capability to monitor the glucose level is based on the fact that a change of friction due to a change in glucose concentration in the arteries and veins causes a distortion of the vibration profile of the vessel.…”

An optical approach allowing the extraction and the separation of remote vibration sources has recently been proposed. The approach has also been applied for medical related applications as blood pressure and heart beats monitoring. In this paper we demonstrate its capability to monitor glucose concentration in blood stream. The technique is based on the tracking of temporal changes of reflected secondary speckle produced in human skin (wrist) when being illuminated by a laser beam. A temporal change in skin’s vibration profile generated due to blood pulsation is analyzed for estimating the glucose concentration. Experimental tests that were carried out in order to verify the proposed approach showed good match with the change of the glucose level at the positive slope stage as it was obtained from conventional reference measurement.
