Nonlinear Ghost Imaging for Scattering-Assisted Terahertz Waveform Synthesis

Terahertz Nonlinear Ghost Imaging is a novel approach that allows for the spatial-temporal sampling of objects with a resolution beyond the diffraction limit. We present our experimental campaign that aims to exploit Nonlinear Ghost Imaging to harness field-level waveform control via complex propagation in scattering media. Agile waveform control is possible at a fundamental level and it is enabled by near-field coupling between a distribution of terahertz source and a scattering medium.
