Biospeckle activity in coffee seeds is associated non-destructively with seedling quality
(Wiley-Blackwell, 2017-03-01)
Seeds age during storage, resulting in a decline in germination and seedling quality. Seed quality tests are important to monitor this decline. However, such tests are usually destructive and require large seed numbers and ...
Determination of maize hardness by biospeckle and fuzzy granularity
(Wiley, 2014-09)
In recent years there has been renewed interest in the development of novel grain classification methods that could complement traditional empirical tests. A speckle pattern occurs when a laser beam illuminates an optically ...

Light intensity independence during dynamic laser speckle analysis
(Elsevier Science, 2016-05)
We explore some different normalizations of current dynamic laser speckle activity measures searching for their performance with respect to the illumination inhomogeneity of the samples. Inertia Moment and Average Value ...
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 ...
The optical analysis of the abdominal wall using the biospeckle after implants of polypropylene mesh in rats
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2009)
PURPOSE: To evaluate an experimental animal model to study the abdominal tissue activity considering its interaction with a polypropylene mesh, through the use of one of the optical phenomena of light Laser, the biospeckle. ...
