T-ray tomography

Abstract: We demonstrate tomographic T-ray imaging, using the timing information present in terahertz (THz) pulses in a reflection geometry. THz pulses are reflected from refractive-index discontinuities inside an object, and the time delays of these pulses are used to determine the positions of the discontinuities along the propagation direction. In this fashion a tomographic image can be constructed.

“…One of the limits of terahertz in imaging is the resolution, which is 0.3 mm for a frequency of 1 THz. This can be improved by operating at higher frequencies or by working in the optical near field [11].…”

“…To sense chemicals, time-domain spectroscopy has been developed [8] . These broadband pulses are used to measure rotational spectra of gases [9] , identify explosives [10] , and obtain THz images [11] . Aside from optical rectifications, other parametric processes in nonlinear crystals can be relatively efficient in converting optical pulses into THz waves.…”
