Abstract
Angle-resolved Mueller matrix element from unpolarized light scattering by micro-bubble in water is simulated using Mie scattering and discrete dipole approximation (DDA) method. This element of Mueller matrix can be used to determine the scattered light intensity to study the possibility of distinguishing the size of micro-bubble. The scattering of unpolarized light beam is simulated for three various wavelengths, 425, 625, and 825 nm. We consider the micro-bubbles sphere 1 - 10 μm with relative refractive indices to water as medium 0.75. The The result show that both Mie and DDA scattering simulation produce similar result and the result shows promising potential of using light scattering to distinguish and measure the micro-bubble sphere diameter size. Clear distinction is shown for 60 – 80 degree of detection angle.
