Long-wave infrared Fourier transform spectroscopy with enhanced and scalable sensitivity
A dual-comb LWIR Fourier transform spectrometer achieves detection limits of 0.3 ppb NH3 and 2 ppb C2H4 in 500 seconds with 20x-40x better sensitivity than prior systems while keeping 0.0027 cm^{-1} resolution.
