Paper Abstract

We present a display showing dynamic speckle local activity as that observe when coherent light illuminates biological samples (biospeckle). Regions differing in their activity are shown as different gray levels. Results obtained with seeds and drying of paint are shown. We propose its use in the determination of seeds viability, detection of corrosion centers and local variations in surface roughness.
