The ability of optical fiber sensors to displace traditional sensors for rotation, acceleration, electric and magnetic field measurement, temperature, pressure, acoustics, vibration, linear and angular position, strain, humidity, viscosity, chemical measurements, and a host of other sensor applications has been enhanced. In this paper is using the shift in the optical fiber Bragg grating(FBG) center wavelength due to mass change. In this paper is presented of the spectral characterization and shaping of FGB by scanning a mass element that affects a small grating fraction at a time, without permanent effects on the optical fiber when the various wavelength and strain is removed. That is, except when the optical fiber for mass is physically damaged.
