A miniaturepolymer Bragg grating (PBG) sensor is fabricated and employed for ultrasonic imaging of seismic physical models (SPMs). The sensing Bragg grating is inscribed into an ultraviolet (UV) gl…
Femtosecond laser point-by-point (PbP) technology can be used as a direct writing method to inscribe fiber Bragg gratings (FBGs) into the cladding of optical fibers. When the refractive index modul…
We propose and demonstrate a method for improving the sensitivity of fiber Bragg grating (FBG) based accelerometers. The method employs a short FBG inscribed in single mode fiber (SMF) with claddin…
We have designed, fabricated, and characterized a fiber-optic three-dimensional vector accelerometer for vibration measurement. The accelerometer is based on fiber Bragg gratings (FBGs) inscribed w…
