We study interaction of structured illumination with randomly scattering media. Based on the equations of scalar diffraction theory we perform a numerical simulations of the propagation of a structured illumination through various scattering media. Applying the continuous sequential algorithm of adaptive phase optimization for focusing a scattered wavefront to a target, we explore the resulting phase distributions at the input and output of the scattering media. We demonstrate that corrected wavefront takes a spherical shape, which can be removed for imaging through the scattering sample. According to the obtained results the using scalar diffraction theory extends the limits of applicability of the sequential adaptive phase optimization algorithm beyond the focusing, making they as broad as in transmission matrix method.
