We combine THz scattering-type scanning near-field optical microscopy (s-SNOM) and synthetic optical holography (SOH) to enable fast, amplitude and phase resolved THz nanoimaging using a THz gas laser and Schottky diode detector. We demonstrate our novel tool by imaging graphene grown via chemical vapor deposition (CVD) and other 2D materials.
