Abstract

Gases which are indicative of combustion and pyrolysis have absorption features in the mid-infrared range. Therefore, it is possible to implement absorption spectroscopy as a detection method to provide real time monitoring of gases in spacecraft. A sensor developed at the University of Central Florida for this purpose was flown on a proof of concept test flight through partnerships with NASA's Columbia Scientific Balloon Facility (CSBF) and the Louisiana State University (LSU) High Altitude Student Payload (HASP). The test flight enabled autonomous operation of the sensor at an altitude of 105,000ft (32km). The sensor utilizes a 4.2 μm light-emitting diode (LED) source, amplitude modulation to characterize CO2 concentration, and frequency modulation to characterize ambient temperature.
