In an embodiment, a method of processing spectrographic data may include receiving optical absorbance data associated with a sample and iteratively computing values for component spectra using nonnegative matrix factorization. The values for component spectra may be iteratively computed until optical absorbance data is approximately equal to a Hadamard product of a pathlength matrix and a matrix product of a concentration matrix and a component spectra matrix. The method may also include iteratively computing values for pathlength using nonnegative matrix factorization, in which pathlength values may be iteratively computed until optical absorbance data is approximately equal to a Hadamard product of the pathlength matrix and the matrix product of the concentration matrix and the component spectra matrix.

Abstract: A spectroscopic microscope includes a laser or other light source which emits light from the entrance aperture of its spectrograph, and also includes a light sensor situated on the microscope sample stage upon which a specimen is to be situated for microscopic/spectrometric analysis. The sample stage is positioned such that the signal from the light sensor is maximized, thereby indicating good alignment between the sample stage and spectrograph. Additionally, the microscope sample stage bears a light source which can emit light to be detected by a light sensor situated at the vantage point of a user/viewer utilizing the microscope, and such a light sensor can simply take the form of a video camera or other image recordation unit associated with the microscope. The sample stage can also be positioned to optimize the signal at the light sensor to signify good alignment between the sample stage and the microscope.

Abstract: The present invention provides an optical sensor for monitoring current or power in a monitored element of a device such as a bridge-wire or hot-wire of electro-explosive devices. The optical sensor comprises an optical sensor made of semiconductor material. The semiconductor material comprises an absorption edge which is sensitive to a temperature variation. The semiconductor material is for placing in thermal contact with the monitored element of the device, whereby, when the current or power varies in the monitored element, it causes a variation in temperature in the semiconductor element and hence a spectral shift of the absorption edge which can be measured and which is representative of current and power variation.

Abstract: A method and system for measuring heat energy of a combustible fluid in which light having wavelengths in the near-infrared is directed into a test cell containing the combustible fluid and portions of the light not absorbed by the combustible fluid and passing out of the cell are spatially dispersed by wavelength, forming a light spectrum that is projected onto a detector. The light spectrum is digitized and inputted into a data processing unit in which it is compared to the actual spectrum of the light source stored in the system to determine the absorbance spectrum of the combustible fluid. The system is spectrally calibrated by identifying known spectral features of the combustible gas absorbance spectrum. To correct for deviations in the original light source spectrum, a light source calibration system is employed. Upon determination of the absorbance spectrum of the combustible fluid, the heating value of the combustible fluid is determined by comparing the absorbance spectrum to a plurality of spectra located within an on-board database.

Abstract: The invention described herein details a protocol to improve analysis and peak identification in spectroscopic data. Bayesian methods are used to automatically identify peaks in data sets. After identifying peak shapes, the method tests the hypothesis that a given number of peaks is found within any given data window. If a peak is identified within a given window, then the likelihood function is maximized in order to estimate peak position and amplitude. This process yields a spectrum with high resolution and minimal artifacts. The method described herein is particularly useful for identifying peaks in data sets obtained from spectroscopy.
