JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Planetary scientists at Brown University have introduced an infrared spectroscopic method for studying olivine, a mineral that provides insights into the formation of the moon, Mars, and other planetary bodies. Informally dubbed “crossover spectroscopy,” the scientists deployed the technique to examine the spectral range in between the visible near-infrared (0.5 to 3 μm) and the mid-infrared ranges (8 to 15 μm). The researchers honed in on the 4 to 8 μm range, and, even more specifically, in the spectral features of olivine at 5.6 and 6.0 μm. A mountain peak at the...Read full articleRelated content from Photonics MediaArticlesSynthesized Nanoresonators Harness Power of IR for Optics and ElectronicsWhen combined with electronics, infrared (IR) light can enable small, fast devices for sensing, imaging, and signaling at the molecular level.
