Abstract: A method of monitoring combustion properties in an interior of a furnace is described. A beam of light is projected through a pitch optic including a pitch collimating lens residing outside the boiler interior. The pitch collimating lens projects the beam through a penetration into the boiler interior. The beam of light projected by the pitch collimating lens is reflected from at least one in-furnace retro-reflector, and received with a catch optic substantially identical to the pitch optic residing outside the boiler interior. The pitch optic and the catch optic may be embodied in the same pitch/catch optic. The pitch collimating lens may also be steered toward another of the at least one in-furnace retro-reflectors. Combustion properties may be calculated for each retro-reflector based on retro-reflector zones within the furnace.

Abstract: A fiber pigtail template assembly includes first and second silicon wafers each having a planar surface with a plurality of corresponding grooves therein extending from a leading edge toward a trailing edge. The plurality of corresponding grooves, with the planar surfaces in abutment and the corresponding grooves aligned define a plurality of fiber channels. The first and second silicon wafers further cooperatively define a receptacle between the fiber channels and the trailing edges of the first and second silicon wafers with the planar surfaces of the silicon wafers in abutment with the grooves aligned. A minor diameter leading portion of an optical fiber is received in each fiber channel and the receptacle is sized to receive major diameter trailing portions of each fiber without causing a bending radius of the fiber sufficient to materially degrade wavelength propagation.

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 optical mode noise averaging device (300) including a multimode optical fiber (302) and means (308) for averaging a modal noise induced signal level variation of light propagating within the multimode optical fiber (302). The device may average modal noise induced signal level variations by cyclically varying an index of refraction of the multimode optical fiber (302) over a select period of time, scrambling a light distribution within the multimode optical fiber (302), or both. The index of refraction of the multimode optical fiber may be cyclically varied by cyclically varying the temperature of the multimode optical fiber (302). Alternatively, the index for refraction may be varied or the light distribution within the multimode optical fiber may be scrambled by cyclically manipulating the multimode optical fiber (302).

Abstract: An apparatus and method are provided employing a single set of reduced-cost optics for (de)multiplexing optical signals whereby the resultant signals have a flat-top response with increased channel spacing. One aspect of the present invention uses an optical interleaver (310) to separate channels from an input multichannel (multiplexed) optical signal (302) with a select channel spacing into, for example, two input signals consisting of alternating channels at twice the select channel spacing. The separated signals are then directed to a multiple-input, such as dual-input, (parallel)(de)multiplexer device (320) which further spacially separates the channels for coupling with single channel transmission fibers (3221-n, 3241-n). The input fibers to the (de)multiplexer are preferably offset relative to each other to accommodate channel shift resulting from the interleaver.
