摘要： A wavelength-locked laser gaseous species monitor including a variable wavelength laser with a laser output actively stabilized to a wavelength at or near an absorption wavelength of the species being monitored. The laser is modulated about that wavelength to establish a modulated output with a known frequency and bandwidth. The modulated output is passed through the sample being monitored and then collected. An even harmonic of the collected output with respect to the modulation frequency is determined, and the presence in the sample of the species being monitored is detected from the even harmonic signal.

摘要： A system and method for optical interrogation and measurement of a hydrocarbon fuel gas includes a light source generating light at near-visible wavelengths. A cell containing the gas is optically coupled to the light source which is in turn partially transmitted by the sample. A spectrometer disperses the transmitted light and captures an image thereof. The image is captured by a low-cost silicon-based two-dimensional CCD array. The captured spectral image is processed by electronics for determining energy or BTU content and composition of the gas. The innovative optical approach provides a relatively inexpensive, durable, maintenance-free sensor and method which is reliable in the field and relatively simple to calibrate. In view of the above, accurate monitoring is possible at a plurality of locations along the distribution chain leading to more efficient distribution.

摘要： A system for controlling the uniformity of combustion over a range of operating conditions in a combustor with a plurality of fuel nozzles. The system includes a number of optical sensors, each sensor comprising an optical probe that collects naturally occurring optical radiation emanating from a segment of the combustor or combustor exhaust, and at least one transducer that receives the radiation collected by the probes, compares the intensity of collected radiation from each sensor in a plurality of spectral pass-bands that are indicative of the fuel/air ratio in the combustor segments, and produces output signals that are indicative of the state of combustion in the combustor segments. A control system receives the output signals from the transducers and in response controls the fuel flow to the fuel nozzles to achieve an output from each of the sensors that has been determined to be indicative of a predetermined state of combustion.

摘要： A system and method for remotely determining at least one of the temperature of, and the relative concentrations of species making up, a hot fluid, based on the spectral structure of radiation emitted from the fluid. Thermal radiation over a field of view including the hot fluid is collected. At least a portion of the emission spectrum from the collected radiation is resolved. The resolved emission spectrum is resolved into spectra that are characteristic of specific emitting species and emitter temperatures. The temperature of, and the relative concentrations of species making up, the hot fluid, are determined from the relative amounts of at least two resolved spectra.

摘要： A spark spectroscopic high-pressure gas analyzer including a spark chamber, having a pair of electrodes, for receiving a sample of the pressurized gas to be analyzed. A voltage is provided across the electrodes for generating a spark in the pressurized gas sample. A selected wavelength band of radiation emitted from the spark discharge in the pressurized gas corresponding to a component to be sensed in the gas is detected. The intensity of the emission in the wavelength band is integrated during the afterglow time interval of the spark emission and a signal representative of the integrated intensity of the emission in the selected narrow wavelength band is employed to determine the proportion of the component in the gas.

摘要： An infrared monitor for measuring the presence of at least one gas phase molecular species including a sample path for containing a sample to be monitored for the molecular species. A sample beam of infrared source emission of the molecular species to be monitored for passage through the sample path is provided to the sample path. The sample beam includes at least one primary spectral emission line which is significantly absorbed by the molecular species. The decrease in the intensity of the at least one primary infrared source spectral emission line passing through the sample path is detected as a function of the absorption of the at least one line by the molecular species present in the sample.
