Methods and apparatus for detecting nitric oxide |
| abstract |
Embodiments of the present invention relate to methods and apparatus for detecting atmospheric NO at signal levels capable of distinguishing the NO isotopologues. More particularly, embodiments of the present invention relate to methods and apparatus for a single photon LIF sensor that pumps a vibronic transition near 215 nm and observes the resulting red shifted fluorescence from about 255 to about 267 nm. Embodiments of the present system uses a NO-LIF measurement fiber-amplified laser apparatus capable of: generating laser linewidth that is sufficiently narrow to resolve the Doppler broadened NO spectrum at room temperature and thereby achieve high signal levels and distinguish the NO isotopologues; generating laser repetition rate sufficient to enable single-photon counting of the fluorescence signal; and having size, weight and environmental robustness allowing for integration onto airborne platforms. |
