Query: Scan-less hyperspectral dual-comb single-pixel-imaging in both amplitude
  and phase   We have developed a hyperspectral imaging scheme that involves a combination
of dual-comb spectroscopy and Hadamard-transform-based single-pixel imaging.
The scheme enables us to obtain 12,000 hyperspectral images of amplitude and
phase at a spatial resolution of 46 um without mechanical scanning. The
spectral resolution is 20 MHz, as determined by the linewidth of a single comb
mode, and the spectral interval is 100 MHz over a spectral range of 1.2 THz
centred at 191.5 THz. As an initial demonstration of our scheme, we obtained
spectroscopic images of a standard test chart through an etalon plate. The
thickness of an absorptive chromium-coated layer on a float-glass substrate was
determined to be 70 nm from the hyperspectral phase images in the near-infrared
wavelength region.
