This method is based on a combination of experimental measurements and numerical simulations and allows obtaining information of domain statistics in disordered structures via the analysis of wavelength dependence of the angular second harmonic diffraction pattern.We acknowledge financial support by Spanish Ministerio de Educación y Ciencia (project FIS2011-29734-C02- 01), US ACQRDECOM (projects W911NF-11-1-0387 and W911NF-12-1-0201) and Generalitat de Catalunya (2014 SGR-957).
