Paper Abstract
The use of dynamic speckle laser, also called biospeckle laser (BSL), presents a series of challenges to its
adoption, as it is the case for its use in real time, and when ones desires to adjust the experimental setup. The
technical analysis of the BSL adopted in real time has reduced spatial resolution of the captured image, while the
adjustment of preparing an experiment still demands the trial of a specialist. In this work two approaches have been
proposed to improve the efficiency of BSL real-time adjustments to support the experimental setup. The use of the
method known as Motion History Image (MHI) was carry out over a series of BSL images. The MHI was the basis
for the implementation of a graphical interface for real-time identification of areas of activity, and then delimiting the
regions of interest. The results showed that the MHI was effective in the reproduction of the activities of speckle
patterns in real time without reducing image resolution, and as an instrument for delimit of regions of activity,
supporting the analyst in the choice of lighting adjustments and image assembling.
