Ultra-High Speed Solid-State FTIR Spectroscopy and Applications for Chemical Defense
Abstract
We introduce a new class of FTIR spectrometers capable of acquiring 6x10(exp 4)-1.4x10(exp 5) interferograms (spectra) per second over the spectral range of 1 micrometers - 12 micrometers, with a resolution of 10 /cm (exp-1) or better. The new FTIR technology is based on the use of birefringence interferometers and employs photoelastic modulators (PEMs) as birefringent elements for ultra-high modulation speed. With characteristic data rates of tens of kHz and wide spectral range these spectrometers are eminently suitable for high-speed spectrally detailed chemical biological (CB) hyperspectral imaging.
