Diffraction Gratings are optical components used to separate light into its component wavelengths. Diffraction Gratings are used in spectroscopy, or for integration into spectrophotometers or monochromators. Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating’s surface.;Fiber-optic grating sensors are intrinsic to the optical fiber, thus capitalizing on its extremely small size and inherent strength and durability. Recent results are provided from a sensor array installed in a road bridge.;A dual system was used to monitor the bridge. Optical ﬁber sensors and conventional foil gages were placed side by side to compare results. Forty-eight optical ﬁber Bragg grating sensors and 48 resistive gages were used to monitor the bridge. The location of the sensors was selected based on results from previous research [1,2] and ﬁnite ;GRATING SENSOR TECHNOLOGY In-fiber optic Bragg grating technology has its origins in the discovery of the photosensitivity of optical fibers by Hill et al. in 1978.12 Later, it was demonstrated13 that a permanent periodic modulation of the refractive index in the core of a photosensitive optical fiber could be produced by transverse ;World of Manufacturers.

Y. (2013) Static vertical displacement measurement of bridges using Fiber Bragg Grating (FBG) sensors.;This is the first bridge in the world to test the prospects of using carbon fiber composite tendons to replace steel tendons. This unique set of measurements was accomplished with an array of 15 Bragg grating fiber optic sensors that were embedded within the precast concrete girders during their construction.;Excitation . Multiple-prism grating laser oscillators can be excited either electrically, as in the case of gas lasers and semiconductor lasers, or optically, as in the case of crystalline lasers and organic dye lasers. In the case of optical excitation it is often necessary to match the polarization of the excitation laser to the polarization preference of the multiple-prism grating oscillator.;Data Acquisition System from Durham Instruments, used to collect information, document, or analyze phenomenon in your product or processes. Finding the right data acquisition system is crucial, to providing the best possible measurement. Interface to virtually all sensor types including: Voltage, current, strain gauges, bridge transducers, load cells, LVDTs, potentiometers, accelerometers ;Welded steel grating is the most popular type among all types of steel grating, also called metal open bar grating. It is also the most widely used type. Welded steel grating is produced through automatically resistance welded. The bearing bars and cross bars are resistance welded under high heat and pressure to form a permanent joint.;28 September 2015 Reflective refractometer based on strong optical coupling between a tilted fiber Bragg grating and a parallel D-shaped fiber Zhongyue Cai , Tuan Guo , Fu Liu , Bai-Ou Guan , Gang-Ding Peng , Jacques Albert
