We describe a holographic method for measuring very high viscosities, up to 1015 poise, or higher. The method consists of detecting small displacements, due to the sample deformation, by the holographic double exposure technique. Measurements performed on amorphous selenium are reported and compared with those obtained with the usual technique, showing that our method gives the correct results. The advantages of the proposed technique are briefly discussed.

Abstract
We describe a holographic method for measuring very high viscosities, up to 1015 poise, or higher. The method consists of detecting small displacements, due to the sample deformation, by the holographic double exposure technique. Measurements performed on amorphous selenium are reported and compared with those obtained with the usual technique, showing that our method gives the correct results. The advantages of the proposed technique are briefly discussed.File in questo prodotto:
