Described herein are systems and methods of tomographic imaging using hyperspectral absorption spectroscopy, which may comprise simultaneously performing absorption measurements at multiple different wavelengths and then performing a tomographic inversion process to exploit the hyperspectral absorption spectroscopy information obtained. The methods and systems described herein can be used to a) exploit the hyperspectral information content to reduce the number of projections required and to improve the stability of the tomographic reconstruction in the presence of measurement errors, b) enable flexible incorporation of various a priori information, c) ameliorate the ill-posedness of the tomographic inversion problem. These advantages are useful in the practical application of tomographic techniques.
