Abstract

We report the realization of a confocal THz microscope based on a ∼ 3 THz quantum cascade laser source. A resolution as low as 67 μm is achieved, with a large contrast enhancement allowed by the confocal geometry. The capability of imaging overlayed objects on close-by planes is also demonstrated.
