We describe a technique for imaging in the terahertz regime using time reversal of single-cycle pulses. Specifically, the time-reversal symmetry of Maxwell's wave equation is exploited to reconstruct the transmission function of a diffracting apertur

We demonstrate the reconstruction of one- and two-dimensional objects by numerically backpropagating measured scattered terahertz transients. The spatial resolution determined by the Sparrow criterion is found to correspond to approximately 30% of th
