ABSTRACT
Results of experiments with laser modulation interference microscopy and the Mueller-matrix scatterometry show that macroscopic scatterers of light waves are present in doubly distilled water free of external solid impurities. The experimental data can be interpreted using a computational model of micron-scale clusters composed of polydisperse air bubbles having effective radii of 70-90 nm. The fractal dimension of such clusters was evaluated as 2.4-2.8 and their concentration appeared to be approximately 10(6) cm(-3).
ABSTRACT
Regular fluctuations in the height of phase profile of isolated neuron were studied by laser interference microscopy. The resultant spectra of frequencies of changes in the phase profile height indicate regular local changes in the optical density and/or geometry of neurons. The frequency spectra for the central and pri-membrane regions of the cells are different.
