  • In order to measure the reflection spectra of fiber Bragg gratings at low cost,a simple measurement system was established based on white light interferometry.After processing the sampled interferogram,the reflection spectra was obtained with the spectral resolution about 3pm.Theoretical analysis of spectral resolution was conducted.Experiments show that the system has a fine spectral resolution.

Abstract: In order to measure the reflection spectra of fiber Bragg gratings at low cost,a simple measurement system was established based on white light interferometry.After processing the sampled interferogram,the reflection spectra was obtained with the spectral resolution about 3pm.Theoretical analysis of spectral resolution was conducted.Experiments show that the system has a fine spectral resolution.
