This study aims to explain the effect of sensor length on dynamic range, linearity and sensitivity of fiber Bragg grating system. The sensing principle is based on tracking of Bragg wavelength shifts caused by the changes in loading condition. A simple experimental setup was utilized in which fiber grating was bonded on a Zinc plate using araldite as an epoxy on both sides of grating and an Optical Spectrum Analyzer to monitor the values of wavelength shift corresponding to the changing applying load. The dynamic range, linearity and sensitivity of fiber Bragg grating system in terms of wavelength shift and longitudinal strain are discussed. From the results, it is inferred that if the sensor length is smaller, then Bragg wavelength shift, longitudinal strain and dynamic range are larger and vice versa. It means that the fiber Bragg grating system is more sensitive to smaller sensor lengths and less sensitive to larger sensor lengths. A linear response has been observed between longitudinal strain and Bragg wavelength shift throughout the measured region.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
