Optical Modeling and Detection of Infrared and Other Spectra
July 12, 2019
Timothy J. Johnson and Tanya L. Myers, the 2019 winners of the Applied Spectroscopy William F. Meggers Award, have been exploring novel methods using infrared (IR) and visible reflectance spectroscopies for identification of target chemicals through derivation of the n and k optical constants. For their winning paper, Johnson and Myers created a spectroscopic library of 57 liquids for which they measured the complex refractive index, data that can be used for optical modeling and other purposes. They shared some of the details of their work with Spectroscopy.
