| titleOfInvention | Open path gas detector with synchronous pulse detection |
| abstract | An open path gas detector for detecting the presence of a target gas (12) in the presence of fog or water vapor. A transmitter (30) transmits flashes (32) of optical energy along a path (10) in an area under surveillance, including energy at a sample wavelength region, which is absorbed by the target gas (12), at a reference wavelength region not significantly absorbed by the target gas, and at a synchronization wavelength region different from the sample and reference wavelengths. A receiver (40) includes a sample channel responsive to the optical energy at the sample wavelength region, a reference channel responsive to optical energy at the reference wavelength region, and a third synchronization channel responsive to the optical energy at the synchronization wavelength region. The receiver (40) detects the target gas (12) and synchronizes operation of the receiver (40) to the transmitter flashes (32) of optical energy using the output of the synchronization channel. |
