Abstract: The present invention relates to a method, apparatus and system for measuring the content of either one or more gas analytes that may be part of a gas. The present invention applies a spectroscopic method that utilizes an extremely narrow linewidth laser beam that is absorbed when its wavelength is swept across the interval containing the absorption line of the analyte. The method, apparatus and system of the present invention is applicable to any analyte in gas phase that is part of a gas mixture, or to any analyte in a plasma phase, as well as analytes in other environments.

Abstract: A device is provided for combining two or more separate components of an optical analysis system, to use common entrance and exit apertures for optical measurements across a measurement space such as a stack, combustion chamber, duct or pipeline, in such way that the optical paths from the respective light sources to detectors are substantially the same, enabling multiple optical measurements over a single optical path or closely aligned optical paths with equivalent ambient conditions such as temperature and pressure distribution and background substance concentrations. The device and a set of interconnectable devices forming a modular system are useful, for example, in absorption spectroscopy, such as for measuring the amount fraction of the chemical constituents of a fluid in a measurement volume.

Abstract: A method of determining the concentration of a species in a portion of a furnace atmosphere is described. The method comprises the steps of measuring first, second and third intensities of electromagnetic radiation in the furnace at first, second and third wavelengths respectively. The third wavelength is selected to be representative of absorption of electromagnetic radiation by the species. A fourth intensity of electromagnetic radiation is calculated, being an estimate of the intensity of electromagnetic radiation in the furnace at the third wavelength absent any absorbing species in the furnace atmosphere. The third intensity and the fourth intensities are used to determine a parameter that is proportional to the concentration of absorbing species in the portion of the furnace atmosphere. Apparatus for carrying out the method is also described.

Abstract: In an apparatus and system for monitoring and communicating emissions data for a diesel engine, an exhaust gas analyzer uses laser light passed through a diffuser to measure the quantity of trace gases and particulates in an exhaust gas outlet from a diesel engine. The analysis chamber possesses superhydrophobic, superhydrophilic, and/or superoleophobic properties to reduce VOC-occlusion of the transparent chamber walls. A radio transmitter, cellular data transmitter, or Smartphone transmits measurement data. In a diagnostic and monitoring system for a diesel engine, the exhaust gas analyzer is in contact with the exhaust gases from the diesel engine, preferably in the tailpipe. A data receiver receives the transmitted measurement data.

Abstract: Methods, storage mediums and systems (MS&S) are provided which successively image an imaging region of an assay analysis system (AAS) as particles are loaded into the imaging region, generate a frequency spectrum of each image via a discrete Fourier transform, integrate a same coordinate portion of each frequency spectrum and terminate the loading of particles upon computing an integral which meets preset criterion. In addition, MS&S are provided which send a signal indicative of whether enough particles are in an imaging region for further processes by an AAS based on the magnitude of integral calculated from an image's frequency spectrum. MM&S are also provided such that the steps of generating a frequency spectrum of each image and integrating a portion of each frequency spectrum are replaced by generating a convolved spatial image with a filter kernel and integrating a same coordinate portion of each convolved spatial image.

Abstract: Devices for reflectance spectroscopy, processes of assembling devices for reflectance spectroscopy, and health care processes of using reflectance optical spectroscopy devices are disclosed. The devices include a light source arranged and disposed to apply broadband light to sample, and a light-receiving feature configured to receive reflected light produced by the applying of the broadband light to the sample. The light-receiving feature is arranged and disposed to direct the reflected light to an optical detection system and isolate the reflected light from the broadband light. The optical detection system is capable of differentiating individual frequencies of the reflected light. The processes of assembling include removably positioning the devices on electronic devices. The health care processes include positioning the devices.

Abstract: A detector for oil condition monitoring includes an optical fiber having a first end and a second end having an end face. A sensor body has a gap in which a sample of the oil may be received and a reflecting surface, the second end of the optical fiber being embedded in the sensor body and having an end face spaced from the reflecting surface across the gap. Light emitted from the optical fiber can pass through the sample of oil and be reflected by the reflecting surface back into the optical fiber. By interferometry of the respective signals, the condition of the oil can be determined.

Abstract: A method and apparatus for improving contrast in prism coupling measurements of waveguide mode spectra, wherein the measured waveguide sample has a surface region of rapidly decreasing index, characterized with normalized slope λ n ⅆ n ⅆ z > 0.0004 . An opaque light-blocking element is placed in the portion of the light beam closest to the plane of the contact between prism and measured sample, on the input side, output side or both sides of the prism. The light blocking element prevents light from the light source to reach a portion of the length of the prism-sample coupling interface along the optical path, prevents light reflected from a portion of the aforementioned length to reach the detector, or both when input and output light-blocking elements are used.
