A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror.

We live in a world bathed in light. We see with light, plants draw energy from light, and light is at the core of technologies from computing to surgical techniques. The field of optics, the subject of this report, concerns harnessing light to perform useful tasks. Light influences our lives today
Intensity modulation technique is an attractive interrogation method for fiber-optic ultrasonic sensors using fiber Bragg gratings (FBGs), in which FBG modulates the intensity of reflected (or transmitted) narrowband light with a wavelength tuned to the slope of the FBG reflection (or transmission) spectrum curve if the vibration or acoustic wave is applied to the FBG and the intensity

Introduction to Diffraction Grating Diffraction Gratings (Ruled and Holographic) Diffraction gratings can be divided into two basic categories: holographic and ruled. A ruled grating is produced by physically forming grooves on a reflective surface by using a diamond tool mounted on a ruling engine. The distance between adjacent
Abstract. A new type of underwater acoustic sensor is proposed with an optical fiber Bragg grating (FBG). Because of the photoelasticity with respect to the refractive index and the elasticity of the fiber, the sound pressure in water modulates the Bragg reflection wavelength and, in turn, the intensity of the laser light transmitted through the FBG fiber.
Diffraction grating, component of optical devices consisting of a surface ruled with close, equidistant, and parallel lines for the purpose of resolving light into spectra. A grating is said to be a transmission or reflection grating according to whether it is transparent or mirrored—that is, whether it is ruled on glass or on a thin metal film deposited on a glass blank.

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.

In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.
