Determination of characteristics of anomalous light scattering in the gradient solutions using electronic speckle-pattern interferometry control of concentration distribution

“…The key point of the ESPI measurement procedure is CCD-based detection of the light intensity distribution (referred to as a specklegram) in the resulting speckle wave at different phase shifts of the reference wave. The shifts used commonly are 0, π/2 and π, or 3π/2 for more accurate measurements [12,13].…”

“…[12] as a high-precision approach for carrying out that task. Earlier it has been applied at the Research Institute of Physics, I. I. Mechnikov Odesa National University, Ukraine, for studying small mechanical displacements and strains, analysing phase structures of biological microobjects [13], etc. The method determines refractive index changes in the whole volume of the measuring cell with no scanning.…”
