Abstract

Dynamic laser speckle or biospeckle has become an important tool to investigate biological activity. Now, we present a method to study the viability of seed using dynamic laser speckle in frequency domain. Compared with other traditional method such as Fujii, our method has been demonstrated to be more accurate and we can evaluate the level of seed viability. The results obtained in experiment on both lived and died seeds are shown as examples
