Abstract :
Laser speckles produced from living objects is called ´bio-speckles´. Bio-speckles observed from the human skin contains information about blood flow in dermal capillarities, heartbeat, and other physiological activity. The time sequence of bio-speckles is a kind of complex fluctuation and has a certain degree of briskness. The thickness of skin will influence the briskness of bio-speckles.
