Faithful non-linear imaging from only-amplitude measurements of incident and total fields.

摘要: Applicability of inverse scattering based imaging procedures can be broadened by developing new approaches exploiting only amplitude data. As a matter fact, this open the way to simpler and less expensive measurement set-ups. In respect, two-step procedure for solving electromagnetic nonlinear problems from measurements total field has been recently proposed [1,2]. However, in these latter both phase incident are still required. contribution, we show possibility achieving information measured distribution on observation domain. particular, three steps technique which exploits fields developed. The tested against benchmark experimental data available literature. obtained results fully confirm faithful reconstructions unknown targets without performing any approximation equations involved problems.
