We report Fourier transform infrared spectro-microtomography, a nondestructive three-dimensional imaging approach that reveals the distribution of distinctive chemical compositions throughout an intact biological or materials sample. The method combines mid-infrared absorption contrast with computed tomographic data acquisition and reconstruction to enhance chemical and morphological localization by determining a complete infrared spectrum for every voxel (millions of spectra determined per… 
Synchrotron-Based Three-Dimensional Fourier-Transform Infrared Spectro-Microtomography of Murchison Meteorite Grain
TLDR
N nondestructive, three-dimensional, microscopic, infrared (IR) spectral in-situ imaging of an extraterrestrial sample is demonstrated to help elucidate the origin and evolution of meteoritic compounds as well as parent body processes without damaging or altering the investigated samples.
Single-cell analysis using Fourier transform infrared microspectroscopy
ABSTRACT Fourier transform infrared spectroscopy (FTIR) is a well-established, non-destructive method of obtaining chemical information from biological samples such as tissues and cells. This review
Hyperspectral Three-Dimensional Fluorescence Imaging Using Snapshot Optical Tomography
TLDR
This work demonstrates hyperspectral 3D imaging using Snapshot projection optical tomography (SPOT) and Fourier-transform spectroscopy (FTS), which allows us to instantaneously acquire the projection images corresponding to different viewing angles.
3D infrared thermospectroscopic imaging
TLDR
This work reports unique data evidence that 3D thermo-chemical information in complex semi-transparent media can be obtained using the proposed 3DITI method, and presents new problems in the acquisition, storage and processing of big data.
Spatially Resolved Two-Dimensional Infrared Spectroscopy via Wide-Field Microscopy.
TLDR
The first wide-field microscope for measuring two-dimensional infrared (2D IR) spectroscopic images is reported, which has diffraction-limited spatial resolution and enhanced contrast compared to FTIR microscopy and is found to have nonlinear scaling of the 2D IR signal to the absorptivity coefficient for the vibrational modes.
Infrared Spectroscopic Imaging Advances as an Analytical Technology for Biomedical Sciences.
TLDR
The combination of vibrational mid-infrared (IR) spectroscopy and microscopy is especially attractive since the fundamental vibrational modes of samples are coincident with optical frequencies, thereby absorbing a large fraction of incident light and providing a strong signal.

Ultrafast 2D IR microscopy.
We describe a microscope for measuring two-dimensional infrared (2D IR) spectra of heterogeneous samples with μm-scale spatial resolution, sub-picosecond time resolution, and the molecular structure
Three-dimensional mid-infrared tomographic imaging of endogenous and exogenous molecules in a single intact cell with subcellular resolution.
TLDR
A method and protocols are provided that overcome the challenge in which tilt-series infrared tomography is used with a standard benchtop infrared microscope and gives access to the quantitative 3D distribution of molecular components based on the intrinsic contrast provided by the sample.
