Compact, UAV compatible 2D Spectrometer for multi-species atmospheric gas analysis

Abstract

We present an UAV compatible spectrometer designed for sampling air pollutants in remote locations. Relying on a custom-made Multi-Pass Cell and a 3-5 µm broadband supercontinuum light source, it takes advantage of an uncooled MWIR camera to record 2D cross-dispersed molecular absorption spectra.
