Query: Multilevel Illumination Coding for Fourier Transform Interferometry in
  Fluorescence Spectroscopy   Fourier Transform Interferometry (FTI) is an interferometric procedure for
acquiring HyperSpectral (HS) data. Recently, it has been observed that the
light source highlighting a (biologic) sample can be coded before the FTI
acquisition in a procedure called Coded Illumination-FTI (CI-FTI). This turns
HS data reconstruction into a Compressive Sensing (CS) problem regularized by
the sparsity of the HS data. CI-FTI combines the high spectral resolution of
FTI with the advantages of reduced-light-exposure imaging in biology.
  In this paper, we leverage multilevel sampling scheme recently developed in
CS theory to adapt the coding strategy of CI-FTI to the spectral sparsity
structure of HS data in Fluorescence Spectroscopy (FS). This structure is
actually extracted from the spectral signatures of actual fluorescent dyes used
in FS. Accordingly, the optimum illumination coding as well as the theoretical
recovery guarantee are derived. We conduct numerous numerical experiments on
synthetic and experimental data that show the faithfulness of the proposed
theory to experimental observations.
