Paper Abstract

The dynamic speckle analysis has been done because speckle interference began to be evaluated as an important source of information, especially those related to biological samples under laser beam. The biospeckle is a phenomenon produced naturally when biological material is illuminated by laser light. If it is possible to record the temporal history of the phenomenon, it will be possible to identify, in a seed, areas with different activity. Biospeckle or dynamic speckle can be used as a method for analysing activity, biologic or not, from materials illuminated with laser beam. The Spatial Temporal Speckle (STS) contains data of time information of dynamic speckle and it is used as input for many techniques allowing the analysis of the activity which is being monitored. This paper presents the results of analysing biospeckle data using fractional order Fourier transform, coefficient filtering and reconstruction, with a novel approach to increase the information obtained.
