摘要： A system is provided for monitoring a relative displacement of a pair of end-winding components. The system includes a structure mounted to the end-winding components at an angle with respect to the end-winding components for monitoring the relative displacement. The system further includes an optical fiber with a first portion including a fiber Bragg grating mounted to a surface of the structure to experience a strain resulting from a strain of the structure due to the relative displacement. The optical fiber includes a second portion internally routed through in the structure to the first portion mounted to the surface. The structure is configured so that the strain produced by the structure limits a magnitude of the strain of the fiber Bragg grating within a predetermined range over a span of the relative displacement of the end-winding components.

摘要： An optical gamma thermometer includes a metal mass having a temperature proportional to a gamma flux within a core of a nuclear reactor, and an optical fiber cable for measuring the temperature of the heated metal mass. The temperature of the heated mass may be measured by using one or more fiber grating structures and/or by using scattering techniques, such as Raman, Brillouin, and the like. The optical gamma thermometer may be used in conjunction with a conventional reactor heat balance to calibrate the local power range monitors over their useful in-service life. The optical gamma thermometer occupies much less space within the in-core instrument tube and costs much less than the conventional gamma thermometer.

摘要： A blanket or article of wearing apparel for a subject such as an infant. A fiber optic temperature sensing element is integrated into the fabric by a process such as weaving. The temperature sensing element is a optic fiber having inscribed therein one or more fiber Bragg grating sensors such that a light is introduced into the optic fiber and that light directed onto the subject at a grating interface. A return light signal is received, either by a reflectance mode or a transmission mode, where the return light signal has a wavelength shift indicative of the temperature of the subject by Bragg resonant effect. Higher temperature sensitivity is obtained with a metal material of a high thermal expansion coefficient that is coated around the fiber sensor cladding.

摘要： The present techniques provide methods and systems for recording micro-holograms on a holographic disk using a plurality of counter-propagating light beams in parallel. The parallel counter-propagating light beams overlap to form interference patterns on a data layer and over multiple data tracks in the holographic disk. Rotating the disk enables the parallel recording of micro-holograms over multiple data tracks, thus reducing recording time. Further, the illumination pattern may include illuminated spots and non-illuminated regions, such that each illumination spot may cover a relatively small fraction of the data layer plane, possibly controlling the depth spread of the recorded micro-hologram. In some embodiments, data in the parallel signal beams may be retrieved from a master holographic disk or may be modulated into the parallel signal beams.

摘要： A fiber gas sensor including a core fiber comprising at least one Bragg grating region, a fiber cladding in contact with the core fiber along an entire length of the core fiber, and a sensing matrix structure disposed upon the outer surface of the fiber cladding along a portion of the length of the fiber cladding and surrounding the fiber Bragg grating region. The sensing matrix structure comprising a bonding layer disposed on the outer surface of the fiber cladding layer, a nano-structured trampoline matrix layer disposed on the outer surface of the bonding layer and a capping layer disposed on the outer surface of the matrix layer. The thermally modulated response amplitude of the fiber gas sensor is found to linearly depend upon the gas molecular weight, and can be directly used to determine heat specific capacity ratio of Cp/Cv.
