About this technology
Overview
For remote sensing spectrometers, wavelength-scanned laser emissions are used to capture the absorption spectrum of targets to perform measurement of soil and/or gas. Previous techniques to accomplish these measurements have involved combining multiple fixed wavelength lasers to detect a single species, limiting the scope and effectiveness of the instruments. This new technology alleviates this problem.
