The Review of Laser Engineering
This paper reviews the work on the dynamic speckle phenomena observed in the light field scattered from living objects. The dynamic speckles produced from living objects are called "bi o-speckles" and fluctuate temporally due to various physiological movements to maintain their lives. This fluctuation of bio-speckles is clearly different from that of speckles produced from the movement of usual diffuse objects such as a ground glass. Dynamic properties of biospeckles are briefly discussed ondoi:10.2184/lsj.18.5_321 fatcat:fsdzc7ruajdqjay2yf6zfpflie
