    Abstract: A photonic measurement system, such as an atomic absorption spectrometer, includes source, sample and detection modules that are interconnected by fiber optic cables. A first set of fiber optic cables guides light from one or more light sources in the source module to each of at least two analysis chambers in the sample module. A second set of fiber optic cables guides light from the analysis chambers to a detector in the detection module. The detector provides to a processing sub-system signals that correspond to intensities of the guided light. One analysis chamber is selected to perform a sample analysis at a given time, and the processing sub-system processes the signals associated with the selected analysis chamber as measurement signals. The processing sub-system may further process the signals associated with a given non-selected analysis chamber as reference signals.

    Abstract: The present invention concerns a new optical photometry system for on-line analysis of industrial fluid streams. The invention is a general purpose optical photometer, capable of absorption, fluorescence and reflectance measurements at single wavelengths in the ultraviolet, visible and near infrared spectral ranges. Light signals generated by the light source are carried between a central photometric console and remote analysis sites by fiber optic cables. The return light signals are compared with a standard to make the desired analysis.

    Abstract: A device for measuring particle emissions of an internal combustion engine, in particular the soot concentration in the exhaust gas, has a signal transmission route, located between a transmitter and a receiver, which traverses a flow of exhaust gas carried in an exhaust gas tube of the engine. To avoid soiling of the active elements of the transmitter and receiver that would cause inaccuracies in measurement, the signal transmission route is embodied as a beam of light, which passes through two diametrically opposed openings in the wall of the exhaust tube. The light-admitting openings are each closed with a respective transparent disk. The disks are heatable and are heated to a temperature above the burnoff temperature of the particles. Appropriate light emitting and receiving elements are used in combination with appropriate heating and evaluation circuits which indicate the soot concentration and which control fuel input to change the soot concentration.

    Abstract: Systems and methods for performing optical spectroscopy using a self- calibrating fiber optic probe are disclosed. One self-calibrating fiber optic probe includes a sensing channel for transmitting illumination light to a specimen and for collecting spectral data of the specimen. The spectral data includes the illumination light diffusely reflected from the specimen at one or more wavelengths. The self-calibrating fiber optic probe may also include a calibration channel for transmitting calibration light. The calibration light and the illumination light are generated simultaneously from a common light source. The calibration channel collects calibration spectral data associated with the calibration light contemporaneously with the collection of the spectral data of the specimen.
