Abstract: Validation verification data quantifying an intensity of light reaching a detector of a spectrometer from a light source of the spectrometer after the light passes through a validation gas across a known path length can be collected or received. The validation gas can include an amount of an analyte compound and an undisturbed background composition that is representative of a sample gas background composition of a sample gas to be analyzed using a spectrometer. The sample gas background composition can include one or more background components. The validation verification data can be compared with stored calibration data for the spectrometer to calculate a concentration adjustment factor, and sample measurement data collected with the spectrometer can be modified using this adjustment factor to compensate for collisional broadening of a spectral peak of the analyte compound by the background components. Related methods, articles of manufacture, systems, and the like are described.

Abstract: A hand-held, self-contained, battery-powered test instrument for analyzing composition of a sample includes an exciter for exciting at least a portion of the sample, a compact cross-dispersed spectrometer for receiving an optical signal from the excited portion of the sample and a processor for processing spectral data about the optical signal from the spectrometer. The exciter may include a spark generator and a counter electrode, a laser or other device for generating the optical signal from the sample portion. The spectrometer has a wavelength range broad enough to enable the test instrument to detect and determine relative quantities of carbon, phosphorous, sulfur, manganese, silicon, iron and other elements necessary to identify common alloys. The spectrometer includes a structural member made of a light-weight material having a small coefficient of thermal expansion (CTE). The spectrometer is dimensionally stable over a range of expected ambient temperatures, without controlling the temperature of the spectrometer.

Abstract: The innovation uses the response of media to electromagnetic (EM) signals in order to identify them. When EM sources are directed at a target medium, a response is obtained from an EM detector observing the event. By comparing a measured response to a library of known profiles, one or more likely candidates for the target medium can be determined.

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.
