Abstract: A device is useful for determining the composition of fluids, in particular the constituents of exhaust gases of internal combustion engines. A light beam (32, 31) passes through the waste gas along the length of a measurement section (29) and becomes more or less weakened or modified in function of the content of the constituents. The light signal received is advantageously recorded by a measurement section light sensor (18), which is shielded from the light source (14) that emits the light, and is evaluated in relation to the original light emission in an evaluation circuit (26). The device lends itself to simple and accurate determination of the turbidity of the waste gas or of the content of optically active constituents in a fluid or gas.

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: A low cost optical system which incorporates a low ultraviolet output tungsten halogen light source and solid state photodetectors and circuitry in such a way as to provide reliable fluorometric test results. The attainment of reliable results using such components is made possible by incorporating highly ultraviolet transmissive optics to maximize ultraviolet light throughput and by using solid state circuitry together with a filter wheel having both light blocking and light passing regions in a manner which fully accounts for noise and dark signals associated with solid state photodetectors.

Abstract: There is disclosed herein a reference system for a fluorometer designed to detect very low levels of materials tagged with fluorophores. There is also disclosed an optical system for use in such a system which improves the signal to noise ratio. The reference system utilizes pulsed arc light excitation which excitation pulses are directed onto a flow cell containing the fluorescent dye. Fluorescent light emitted from the dye is guided to a photomultiplier tube which converts it to electrical pulses. A portion of each excitation light pulse is guided by a light pipe onto a PIN diode light detector which converts these light signals to electrical pulses. A LED reference light source is pulsed to generate a plurality of reference light pulses one of which occurs between each excitation pulse. A portion of each of these pulses is guided to each of the two light detectors and two more series of electrical pulses are generated. A microprocessor then reads the four electrical pulses resulting from each pair of light pulses and performs a computation on the resulting numbers which indicates the relative concentration of the target concentration being assayed. The optical system masks the excitation light pulses and the emitted light pulses to minimize the amount of scattered excitation light than gets into the emitted light optical channel and to control the location and size of the image projected onto the photomultiplier tube to stabilize its output signal. The light pipe and an output lens spatially integrates the image of the excitation light mask and focusses this light on the PIN diode so that the dancing image of the arc does not wander off the face of the PIN diode and destabilize its output signal. The action of the flow cell fluid contents spatially integrates the fluorescent light thereby helping to stabilize the output of the photomultiplier tube.

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.
