Abstract: A method includes directing a portion of a laser beam output from a laser along a secondary beam path toward a detector, the secondary beam path being distinct from a main beam path of the laser beam; generating a bandwidth selective interference pattern of the laser beam on the detector; detecting, at the detector, a width of a fringe within the interference pattern to thereby measure measuring a bandwidth of the laser beam; and homogenizing the laser beam traveling along the secondary beam path prior to generation of the bandwidth selective interference pattern. The homogenizing includes diffusing the laser beam; and introducing a time dependent, position dependent, or both time and position dependent random modulation to the wavefront of the laser beam to reduce fluctuations in the detected fringe width and to reduce the influence of spatial coherence of the laser beam on the detected interference pattern.

Abstract: Thermodynamic properties of a natural gas stream can be determined in real time utilizing modeling algorithms in conjunction with one or more sensors for quantifying physical and chemical properties of the natural gas. A first data signal produced by a first sensor can include intensity as a function of wavelength. At least one region in the wavelength range outside of a selected absorption transition can be fitted to a function to obtain a zero-absorption baseline, and a carbon dioxide concentration can be determined based on a line strength at the selected absorption transition corrected by the zero-absorption baseline. A total hydrocarbon concentration in the gas stream can be inferred based on a database of characteristic natural gas concentrations, and an algorithm can be implemented that determines an energy content of the gas stream. Related techniques, apparatus, systems, and articles are also described.

Abstract: Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include an unstablized laser and thermal imaging camera that allow for detection of gas that absorbs at least some of the wavelength of operation of the unstablized laser. The devices can be operated at a low-power density for safety and/or may be configured to mitigate wavelength hopping associated with unstablized laser light sources.

Abstract: A spectroscopy system is provided which is optimized for operation in the VUV region and capable of performing well in the DUV-NIR region. Additionally, the system incorporates an optical module which presents selectable sources and detectors optimized for use in the VUV and DUV-NIR. As well, the optical module provides common delivery and collection optics to enable measurements in both spectral regions to be collected using similar spot properties. The module also provides a means of quickly referencing measured data so as to ensure that highly repeatable results are achieved. The module further provides a controlled environment between the VUV source, sample chamber and VUV detector which acts to limit in a repeatable manner the absorption of VUV photons. The use of broad band data sets which encompass VUV wavelengths, in addition to the DUV-NIR wavelengths enables a greater variety of materials to be meaningfully characterized. Array based detection instrumentation may be exploited to permit the simultaneous collection of larger wavelength regions.
