Hyperspectral Imaging using a THz dual-comb source

Not Accessible

Your library or personal account may give you access

Abstract

We use a THz dual-comb optical source to perform high-speed hyperspectral imaging in the 300 GHz range with high sensitivity field-effect transistor-based THz detectors. First hyperspectral imaging results of different samples are shown using a scanning system, demonstrating the localization of interesting spectral features in the specimens.
