And speaking of 3D technology, here's a relatively new label: Fourier Transform Infrared (FTIR) spectro-microtomography. According to Kurzweil News, this involves a non-destructive 3D imaging technique that provides molecular-level chemical information of unprecedented detail on biological and other specimens with no need to stain or alter the specimen. In full color, no less! According to Michael Martin, an infrared imaging expert at Berkeley Lab’s Advanced Light Source: "While the most immediate applications will be in biomedical imaging, I think full color FTIR spectro-microtomography will also be applicable to imaging 3D structures in biofuels, plants, rocks, algae, soils, agriculture and possibly even studies of art history where different layers of paints could be revealed.” Mouth-full-of-a-name notwithstanding, this could be pretty exciting!
