Abstract:
Modulation interference microscopy and measurements of the elements of the light scattering matrix showed that doubly distilled water purified from solid impurities contains macroscopic scatterers in the form of micron clusters formed by polydisperse air bubbles with the effective radius 70 — 90 nm. The fractal dimension of clusters lies within 2.4 — 2.8 and their concentration is ~106 cm-3.
