Abstract: A method and apparatus for determining the concentration of a constituent in a fluid by directing a beam of light into the fluid and sensing the intensity of components of the light emerging from the fluid at various wavelengths. The light emerging from the fluid can be light that has been attenuated by absorption or induced by fluorescent radiation. The effect of scattering on the light is minimized by normalizing the component intensities, which are then applied to an algorithm incorporating weighting factors that weighs the influence that the intensity at each wavelength has on the determination of the concentration of the constituent for which the algorithm was developed. The algorithm is developed by a regression analysis based upon a plurality of known mixtures containing various concentrations of the constituent of interest.

Abstract: Radiant energy is transmitted to a probe element including an interior conical reflecting surface and a fluid sample chamber. Portions of the light which have been transmitted, partially attenuated, or scattered by a fluid sample in the sample chamber are directed by at least a portion of the interior conical reflecting surface to means for collecting the transmitted, partially attenuated, or scattered light. A stilling valve incorporated into the probe element enables elimination of entrained gas bubbles from the chamber.

Abstract: An undersea probe which can be attached to marine animals for collecting data as to light intensity and temperature in regions where the marine animals travel. The probe is essentially omnidirectional in its light acceptance capability so that light intensity measurements will not be dependent upon any particular orientation of the probe. The probe includes a central optical fiber containing a fluorescent dye enclosed in a transparent or translucent, protective and fouling-resistant sheath. The optical fiber is provided at its outer end with a fiber terminator which blocks entry of light into the end of the fiber. At its opposite inner end, the fiber is coupled to a light detector in a housing which may be implanted in the marine animal. The optical fiber exhibits radial changes in its refractive index to trap light which approaches the surface of the fiber from inside and which makes a small enough angle with that surface. Such light is propagated along the fiber to the light detector.

Abstract: An apparatus for emitting and receiving light comprises an emitter, which consists of a light source (5) and a concave mirror (7), and a receiver which receives light from the emitter and which is connected to analyzing equipment (3). Furthermore, the receiver comprises a concave mirror (9) which is disposed behind the mirror (7) of the emitter and whose diameter is larger than that of the mirror (7) of the emitter and whose focus is located in front of the light source (5). In the focus of the mirror (9) is positioned one end of an optical fibre (19) for transmitting the received light to the analyzing equipment (3). Moreover, the apparatus comprises a retroreflector unit (17) for reflecting the light from the emitter to the receiver, and a movable shielding element (11) which is provided between the light source (5) and the optical fibre (19) and which prevents, in a first position, the light from the light source from reaching the optical fibre directly, and lets through, in a second position, the light from the light source directly to the optical fibre.

Abstract: A device is proposed for measuring the composition of fluids, in particular of constituents of exhaust gases from internal combustion engines, in which a light ray (32, 31) is used to irradiate the exhaust gas to be measured over the length of a measuring section (29) and is weakened or changed more or less, depending on the content of constituents. The light signal being received is advantageously registered by a measured length light receiver (18) which is shielded light-tight against the light emitting light source (14) and is evaluated in relation to the original light emission, in an evaluation circuit (26). In this simple way, accurate information is obtained of the exhaust gas clouding and of the loading of a fluid or gas with constituents which are optically active.
