    Abstract: PROBLEM TO BE SOLVED: To provide an optical mode noise averaging device (300) that includes a multi-mode optical fiber (302), and a means (308) for averaging variations of signal level in an optical level of an optical signal. SOLUTION: The device averages the variations of the signal level induced by mode noise by periodically changing a refractive index of the multi-mode optical fiber (302) for a selected period or scrambling optical distribution in the multi-mode optical fiber (302), or by both of them. The refractive index of the multi mode optical fiber is periodically changed by periodically changing temperature of the multi-mode optical fiber (302). Alternatively, cyclically manipulation of the multi-mode optical fiber (302) enables the refractive index to be changed, or enables the optical distribution in the multi-mode optical fiber to be scrambled.

The demultiplexer (28) demultiplexes the laser light and optically couples to detectors (25) the selected lasing frequencies of light. Each of detectors (25) is sensitive to one of the selected lasing frequencies. COPYRIGHT: (C)2009,JPO&INPIT

    Abstract: A method of monitoring combustion properties in an interior of a boiler of the type having walls comprising a plurality of parallel steam tubes separated by a metal membrane. First and second penetrations are provided in the metal membrane between adjacent tubes on opposite sides of the boiler. A beam of light is projected through a pitch optic comprising a pitch collimating lens and a pitch relay lens, both residing outside the boiler interior. The pitch relay lens projects the beam through a penetration into the boiler interior. The beam of light is received with a catch optic substantially identical to the pitch optic residing outside the boiler interior. The strength of the collimated received beam of light is determined. At least one of the pitch collimating lens and the catch collimating lens may then be aligned to maximize the strength of the collimated received beam.

    Abstract: An apparatus for multiplexing or demultiplexing optical signals in an optical communication system includes a plurality of optical waveguides aligned generally along the same optical axis each having a propagating end. A reflective grating is optically coupled to the plurality of optical waveguides along the optical axis and has a surface receiving an optical signal emitted from at least one of the optical waveguides. The surface diffracts the optical signals into at least one other of the optical waveguides. A collimating/focusing optic having a select focal length is optically coupled between the plurality of optical waveguides and the reflective grating along the optical axis. The collimating/focusing optic is positioned relative to the propagating ends of the plurality of optical waveguides and the reflective echelle grating to propagate a telecentric optical beam(s) into the at least one other of the optical waveguides.

    Abstract: A method of calibrating an absorption spectroscopy measurement wherein the calibration method includes projecting laser light through a sample of a first quantity of a gas of interest and a second irrelevant quantity of a spectroscopically identical or similar gas (10). The first and second spectroscopic absorptions of the laser light are measured over specific first and second absorption lines. A functional relationship is determined between the first and second measured spectroscopic absorptions and two unknown variables. The function relationships may then be simultaneously solved to determine one or both unknown variables and thereby obtain a measurement relating to the first quantity of the gas of interest, calibrated for the second irrelevant quantity of gas.
