We considered the transfer of multi-spot optical patterns through disordered two-dimensional waveguide arrays with shallow refractive index modulation. In computer simulations, it was uncovered that statistically averaged output intensity distributions of complex inputs retain their structural features for suitable disorder strengths due to the Anderson-like localization of light. To characterize the quality of the input-output pattern similarity, we introduced corresponding criteria and analyzed their variations with the disorder level.
