TLDR
In this article, the authors demonstrate time reversal 3D imaging using single-cycle terahertz pulses, where the photoconductive transmitter and receiver are arranged in a reflection imaging configuration.Abstract:
We demonstrate time reversal 3-D imaging using single-cycle terahertz pulses. The photoconductive transmitter and receiver are arranged in a reflection imaging configuration. The synthesized ring annular detection array can distinguish spatially separated image planes.read more

Time resolved synthetic aperture terahertz impulse imaging
TL;DR: Using a well characterized terahertz (THz) impulse ranging system, this paper demonstrated broad bandwidth imaging at THz frequencies using an inverse synthetic aperture deconvolution technique, demonstrating millimeter and submillimeter resolutions along the cross range and range axes, respectively.

TL;DR: In this paper, a technique for imaging in the terahertz regime using time reversal of single-cycle pulses is described, where the time-reversal symmetry of Maxwell's wave equation is exploited to reconstruct the transmission function of a diffracting aperture by inverting the diffracted fields.
