Abstract
We demonstrate quasi-optical, diffraction-limited two-dimensional image pro duction by means of reflected pulses of terahertz (THz) radiation. A spheri cal mirror is used to form a real one-to-one THz image of two 1-mm-diameter steel spheres, which is then scanned over a THz receiver. Diffraction-limi ted spatial (cross-range) resolution and THz pulse range resolution are sim ultaneously observed. (C) 2001 Optical Society of America.
