Is a Double Lens System Better?

The paper “Non-coplanar gravitational lenses and the ‘communication bridge’” by Viktor T. Toth explores the concept of using multiple gravitational lenses aligned along a central axis to potentially enhance light amplification, a concept referred to as the “gravitational lens bridge.” The study employs various methodologies, including photon mapping and wave theory, to assess whether double-lens systems could outperform single-lens systems in terms of signal amplification. The results, however, indicate that these double-lens systems do not provide additional advantages over traditional single gravitational lens systems.
