The tomographic imaging of chemical species distributions has undergone rapid development in the last 15. years, driven by the combination of key scientific and technological challenges, the emergence of new optoelectronic hardware, and fundamental progress in inverse problems. We describe here the state of the art in chemical species tomography using transmission-based spectroscopic absorption, as well as the key challenges for its future development. The treatment ranges from the infrared spectroscopy of target species and associated spectroscopic techniques, through hardware implementation in optical and electronic systems, to image reconstruction methods. Two case studies illustrate the application of central concepts in the field.
