摘要： An illustrative cavity ring down gas sensor includes an optical cavity for receiving a gas to be detected and at least two electromagnetic radiation sources. The first electromagnetic radiation source may emit a first beam of light having a wavelength corresponding to an absorption wavelength of the gas to be detected, and the second electromagnetic radiation source may emit a second beam of light having a second wavelength that is off of an absorption wavelength of the gas to be detected. The first beam of light may detect a cavity ring down time decay, which is related to the concentration of the gas to be detected. The second beam of light may be used to detect a baseline cavity ring down time decay, which may be used to help increase the accuracy of the sensor by, for example, helping to compensate the concentration of the gas detected by the first beam of light for sensor variations caused by, for example, sensor age, temperature or pressure changes, and/or other conditions.

摘要： A system and method includes a tunable light source and a gas cell configured to detect the presence of gases at terahertz frequencies. The light source is operable to emit a light signal at terahertz frequencies. The gas cell includes at least two high frequency mirrors adapted to reflect signals at terahertz frequencies. The gas cell is adapted to be tuned based on the frequency of the emitted light to obtain a Fabry-Perot resonance of the reflected light signal. A pair of detectors are operable to detect the original light signal and the light signal reflected through absorption paths in the gas cell. The system and method are operable to determine a presence and identity of a gas present in the gas cell.

The system may be a camera-like structure incorporating an infrared sensor, a lens, and an element that could filter out some of the long-wave infrared radiation. The sensor may receive radiation of a scene which forms images on the sensor. The images may be provided to a processor that incorporates one or more modules to determine whether a flame is present in the scene.
