Spectral evaluation of local light scattering behavior in glass particle-dispersed epoxy matrix composite

Local light scattering behavior in glass particle-dispersed epoxy matrix composite was observed at different wavelengths using a wavelength-selective microscope. Observed light scattering behavior had wavelength dependence originated from the dispersion of refractive index difference between the matrix and the particle. Local fluctuation of light scattering in dispersed particle order demonstrates importance of local evaluation of light scattering in diffusive materials with inhomogeneous refractive index distribution.
