Recently the investigation of non-stationary systems exhibiting spatial and dynamic
heterogeneities has propelled the development of innovative optical techniques providing …

Biospeckle laser technique has become an important tool to investigate biological activity in
several areas of science. However, due to the complexity of biological materials it is …

Dynamic speckle has been used in some biologic and industrial applications for the
characterization of transient processes. The time evolution of processes that show the …

Intensity-based pointwise non-normalized algorithms for 2D evaluation of activity in optical
metrology with dynamic speckle analysis are studied and compared. They are applied to a …

For consumers, fresh-cut fruits and vegetables are a convenient product and a healthy
source of fresh food that has nutritional and sensory characteristics similar to those of intact …

A temporal difference method for processing dynamic speckle images is proposed. In the
method two speckle images of an object, separated by a time interval, are subtracted one …

Statistical processing of speckle data enables observation of the speed of processes. In
intensity-based pointwise dynamic speckle analysis, a map related to speed's spatial …

This work is part of studies of drying of paints using dynamic speckle interferometry (DSI), a
technique based on the use of laser light. DSI is a non-invasive method that does not disturb …

The laser dynamic speckle phenomenon is a grained and fluctuant interference produced
when a laser light is reflected from an illuminated surface undergoing some kind of activity …

The short drying times of spray paints are of great benefit in some applications, and this
property allows for painting over almost-immediately. However, this fast-drying process …
