The fundamental problems associated with the implementation and exploitation of spectral imaging are: how to record the three-dimensional data cube (two transverse dimensions and wavelength) in ‘real-time’ using a conventional two-dimensional detector and how to invert the recorded data to extract useful and reliable information.  I will describe novel optical techniques that uniquely enable recording of the spectral data cube in a single snapshot, which can be inverted using physical models for light propagation in complex structures to yield quantitative chemical images. Real-world applications range from in vivo biophotonic imaging of oxygen consumption in biomedical research and ophthalmology to thermal infrared imaging of gas spectra.
