Hyperspectral imaging for thermal analysis and remote gas sensing in the short wave infrared

摘要

A novel hyperspectral imaging device based on Fourier transform analysis applied to a low finesse scanning Fabry-Perot (F-P) interferometer has been demonstrated in the short wave infrared (SWIR) region. The technique allows the realization of a lightweight and compact instrument yet allowing much faster and/or better quality hyperspectral images with respect to classical instruments based on a dispersive means or on a tunable band-pass filter. The potentialities in spectroscopic applications like remote gas sensing are presented as well as accurate thermal imaging capabilities.
