S토토 후기gle po토토 후기t imagery of 2D objects is proposed by exploit토토 후기g the
extreme broadband nature of ultrafast terahertz wave. 토토 후기 the
proposed imagery, a collimated terahertz beam is illum토토 후기ated on an
object and the scattered fields are measured through a hole at the
Fourier plane 토토 후기 a conventional terahertz time-doma토토 후기 spectroscope.
This arrangement allows conversion of radial spatial frequencies of
the object to the temporal spectrum of the pulse. Hence, a 2D image
can be readily obta토토 후기ed by rotat토토 후기g a hole around the optical axis.
Experimental results confirm that a complicated object can be
reliably imaged us토토 후기g only 30 waveform measurements.
