Laser Speckle Imaging Revels Drying Dynamics of Adhesive

What is it about?

We present experimental demonstration of laser speckle intensity based methods to follow the drying process of white adhesive. Results obtained using graphical methods such as temporal LASCA, GD, Fujii and parameterized Fujii as well as numerical methods of Inertia moment and temporal correlation show that qualitative and quantitative evaluation of spatial temporal speckle activities can be used to monitor drying process of adhesives. Statistical Tukey’s test for the mean values of inertia moments at 5% significance level allowed differentiating different stages of drying.
