Abstract
If light interacts with media, it will naturally transform into structured light, spatially varying in its properties as amplitude, phase, and/or polarization and carrying information about the interacting medium. Going to the nano-regime, media information is typically hidden in the non-paraxial properties of light, including its 3D polarization states. However, with standard imaging techniques, this information is not directly accessible and stays invisible. We present how customized non-paraxial laser light fields can serve as a sophisticated tool for revealing hidden media information by selective dipole excitation. Additionally, we further advance our system by implementing a dielectric metasurface for information extraction.
