20140185998 | METHOD AND APPARATUS FOR FIXING STRAINED OPTICAL FIBERS AGAINST CREEP AND TEMPERATURE AND STRAIN SENSORS USING SAID TECHNOLOGY - Optical fiber anchors accomplishing low creep confinement or fixing of a section of optical fiber in an assembly compact enough to be used conveniently as an anchor or as an enabling part of a strain or temperature sensor while retaining low optical losses and the original buffer coating to prevent the fiber from being exposed to abrasion and other influences that could lead to breakage. A rigid body is used that is mechanically stiff and hard enough to prevent the fiber from cutting into it or distorting the medium or substrate when subjected to stress, even over a long period of years. Trapping can be accomplished by molding the bent fiber into the substrate or body, adhesively bonding or soldering the optical fiber into a confining curved groove in a body or substrate. | 07-03-2014 |

20110058768 | COMPACT FIBER OPTIC SENSORS AND METHOD OF MAKING SAME - A compact, optically double-ended sensor probe with at least one 180° bend provided in the optical fiber in close proximity to a fiber Bragg grating temperature sensor suspends the optical fiber within a casing in such a way that the expansion and contract of the probe casing will not materially influence the temperature reading of the fiber Bragg grating by adding time varying or temperature varying stress components. | 03-10-2011 |
