The principle is equivalent to a band-pass filter, whichcompletely ref In order to cope with the application oflarge scale (requiring a large number of sensing points) in the engineeringfield, we have launched the sensing fiber project, that is, in the process offiber The fabrication of fiber Bragg grating (FBG) is generally realized by using ultraviolet laser and phase mask, which has great advantages in both difficulty and mass production. Fiber Bragg grating (FBG) is an importanton-line fiber filter device, which is usually realized by periodicallymodulating the refractive index of fiber core with UV laser and phase mask. Itcan reflect Opticalfiber lasers in industry have led to a high rate of growth in this industryevery year. Fiber Bragg Grating (FBG) ... |
