Abstract:
Terahertz (THz) computational imaging has recently attracted
significant attention thanks to its non-invasive, non-destructive,
non-ionizing, material-classification, and ultra-fast nature for 3D
object exploration and inspection. However, its strong water
absorption nature and low noise tolerance lead to undesired blurs and
distortions of reconstructed THz images. The performances of existing
methods are highly constrained by the diffraction-limited THz signals.
In this talk, we will introduce the characteristics of THz imaging and
its applications. We will also show how to break the limitations of
THz imaging with the aid of complementary information between the THz
amplitude and phase images sampled at prominent frequencies (i.e., the
water absorption profile of THz signal) for THz image restoration. To
this end, we propose a novel physics-guided deep neural network
design, namely Subspace-Attention-guided Restoration Network (SARNet),
that fuses such multi-spectral features of THz images for effective
restoration. Furthermore, we experimentally construct an ultra-fast
THz time-domain spectroscopy system covering a broad frequency range
from 0.1 THz to 4 THz for building up
temporal/spectral/spatial/phase/material THz database of hidden 3D
objects.
