Extraction of dynamic speckle activity information from digital holograms
(Society of Photo-Optical Instrumentation Engineers, 2016-12)
In this work we show how dynamic speckle information can be extracted directly from digital holograms. This allows improving the analysis and characterization of dynamic phenomena by combining dynamic speckle with digital ...
Dynamic speckle analysis using multivariate techniques
(IOP Publishing, 2015-03)
In this work we use principal components analysis to characterize dynamic speckle patterns. This analysis quantitatively identifies different dynamics that could be associated to physical phenomena occurring in the sample. ...
Two simple methods for overall determination of mobility in dynamic speckle patterns
(Elsevier, 2013-12)
In this work, we present two simple methods to quantify the mobility of dynamic speckle patterns. The first method is based on the averaged pixel intensity differences between subsequent frames, while the second simply ...
Dynamic speckle study of microbial growth
(Society of Photo-Optical Instrumentation Engineers, 2015-08)
In this work we present a characterization of yeast dynamic speckle activity during growth in an isolated agar culture medium. We found that it is possible to detect the growth of the microorganisms even before they turn ...
