Abstract
A system for use in monitoring blood circulation data of a user is disclosed. The system comprising a monitoring unit comprising at least one light source unit configured for providing and directing coherent illumination onto at least one selected inspection region on the user's body, and a collection unit configured for collecting light returning for at least a portion of the inspection region and generating a plurality of image data pieces associated with secondary speckle patterns in the collected light returning from said regions; and a control unit configured and operable for receiving said plurality of image data pieces, determining correlation functions between speckle patterns in consecutive image data pieces, processing said correlation functions for determining data indicative of at least two heart rate data sequence indicative of heart rate of the user, and determining data indicative of circulation pressure of the user in accordance with said data indicative of heart rate of the user measured at said first and second monitoring regions.
