Laser Based Absorption Sensors for Trace Gas Monitoring in a Spacecraft Habitat 1999-01-2151
The use of a unique laser based compact gas sensor based on continuous wave (cw) difference frequency generation using non-linear optical conversion is reported for on-line, real-time measurements of H2CO, CH4 and H2O. Specifically, this portable sensor was used to monitor H2CO levels with a sensitivity of ~30 ppb during the 90 day Lunar-Mars Life Support Test Program conducted at NASA-JSC in 1997.
