Event Picture:

Surface plasmon resonance microscopy does not have a sufficiently high lateral resolution due to the fact that terahertz (THz) surface plasmon polaritons propagate over macro distances (~100 ) from their excitation spot, thereby blurring the observed area, by analogy with a scattering medium. To eliminate this disadvantage, we propose to adapt the single-pixel imaging technique known as ghost imaging (GI). To implement the classical GI for THz SPR microscopy we propose to use spatially modulate light by speckle patterns arising from the reflection of coherent THz radiation (generated by a free electron laser) from a rough metal surface.
