Automated trace gas molecular analyzer using rotational spectroscopy

VDI and OSU are in a strong position to meet the requirements of this SBIR. Building on a strong foundation of closely related sensor work in the millimeter/submillimeter, we will focus our Phase I efforts on the new challenges of this SBIR topic. The chief new analysis challenge is to provide a list of lines that arise from gases that are not in the spectrometer reference catalog. We have already demonstrated the absolute intensity calibration and well defined lineshapes required for the subtraction and deconvolution that are a necessary foundation for this task. To satisfy these requirements and to broaden the range of applications, we have chosen high spectral purity, frequency agile hardware and configurable software. The hardware design will allow multiple frequency bands and flexible physical configurations. This design uses all-solid-state electronic component technologies developed by VDI and demonstrated throughout the frequency band of interest.
