Light scattering of a cataractous lens in the presence of cold cataract

摘要

Abstract: The nuclear part of the cataractous bovine lens was investigated. The angular dependence of the light scattered intensities was measured as a function of temperature. The random density fluctuation theory and the Debye theory for a spherical scatterer were adopted to evaluate size of scattering units. The analysis of the experimental data demonstrates the presence of three kinds of scattering units: aggregates, separation between scattering elements and scatterers responsible to the phase separation. The temperature dependence of the light scattered intensity was used to estimation of the spinodal temperature for the sample. !15
