NASA benefits include the availability of rugged, low cost, airborne compatible instruments for the rapid and precise measurements of important gases such as ozone that will improve our knowledge for predicting and modeling atmospheric dynamics and climate change. This technology will allow for direct detection of Ozone at 1 ppbv levels (potential for sub ppbv) at 10 Hz. This will allow for high resolution ozone mapping from airborne platforms. This methodology is also adaptable to Homeland Security for identification of chemical agents. Direct commercial application areas include environmental sensing and regulatory compliance, atmospheric research, and optical sensing. In addition, this technology has application for gas leak sensing of pipelines, fire detectors for commercial and private aircraft, combustor feedback control sensors, and process control sensors for energy and chemical production industries.
