    Abstract: The current invention considers the spectrum as a multimodal distribution over a list of structures containing the wavelength as the main entry and the other information mentioned above in the list as additional entries. Each line is then given a probability of contributing to the spectral line. In the case of multiple spectral lines, inference between spectral lines and their respective levels of confidence will provide a complete picture of the list of probable emitters with a probability factor for each line in order to provide a quantitative assignment of the spectral lines and profiling for a given spectrum.

    Abstract: Methods and systems for real time, in situ monitoring of fluids, and particularly the determination of both the energy content and contaminants in a gas or oil transmission facility, are provided. The system may include two separate scanning sources to scan two different, but overlapping, NIR ranges, or may involve two separate scans from a single scanning spectroscopy source. The first scan ranges from approximately 1550 nm up through 1800 nm and a second scan concurrently scans at a high resolution across a band from approximately 1560-1610 nm, the wavelength of interest for hydrogen sulfide (though similar scans are contemplated in alternative wavelength ranges for alternative contaminants). The second scan may provide very narrow (0.005 nm) step resolution over just the wavelength of interest for the contaminant and may scan at a substantially higher power level. The spectroscopic optical data from the two scans, however obtained, must then be combined into an analytical processing module containing models that analyze the multi-scan data and yield both energy content and contaminant quantitative data.

    Abstract: A control circuit operably couples to a non-invasive imaging system that utilizes a particular corresponding effective spectrum and receives imaging information as pertains to an object being imaged. The control circuit uses that information to identify the particular corresponding spectrum for the corresponding source of radiation by, at least in part, evaluating candidate spectra as a function, at least in part, of physical likelihood (for example, by identifying a spectrum that is physically unlikely or physically impossible). Evaluating the candidate spectra as a function of physical likelihood can comprise evaluating the candidate spectra with respect to regularization, smoothness, being non-negative, normalization characteristics, monotonic characteristics, envelope limitations, quasi-concave characteristics, and/or consistency with one or more physics models of choice to note but a few options in these regards.

    Abstract: Provided is a method for performing a wavelength calibration of a monochromator with a diffraction grating by casting light from a standard light source whose emission intensity contains a change with a predetermined cycle onto the diffraction grating and measuring an intensity of light reflected by the grating. The method includes the steps of: measuring at least two times the intensity of the reflected light from the grating within the aforementioned cycle at each of the rotational positions of the grating corresponding to a range of wavelengths including a peak wavelength of a bright line spectral light generated by the standard light source; determining an intensity value 201 at each rotational position based on all the measured values obtained at the rotational position; and locating, as the peak wavelength of the bright line spectral light, a wavelength at which the intensity value 201 is maximized.
