Abstract
This Small Business Innovation Research (SBIR) Phase II project will enable Energetiq Technology, Inc. to develop and commercialize an advanced Open-Path FTIR Spectrometer (OPFTIR) instrument for monitoring of atmospheric gases over extended distances. The Phase II technical goals will be the optimization of a high-brightness infrared source and optical subsystem that will enable long path instrument capabilities. For current FTIR instruments the infrared light source is a thermal blackbody, limited to operating temperatures of approximately 1000 C. For OP-FTIR instruments the consequences of relying on such low-brightness light sources are (a) bulky and expensive IR optics; (b) expensive IR detectors; and (c) limited monitoring range ? typically less than a few hundred meters. The laser heated IR light source developed in Phase I has demonstrated greater than 2000C operation. Direct comparison with a standard GlobarTM source shows an improvement in signal amplitude of between 2 and 10 (depending on wavelength) and signal to noise measurements imply an improvement in detectability of from 1.5 to about 6. The broader impacts of this research are in the area of environmental monitoring and potentially in Homeland Security applications. The cost and size of OP-FTIR instruments will be reduced and the range and sensitivity increased. With increased emphasis on monitoring total fluxes of atmospheric pollutants, including global warming gases such as CO2, OP-FTIR instruments will be even more widely used in the future.
