【Abstract】 Based on the technique of fiber grating linear tuning,this paper reports a new method of measuring fiber grating transmission spectra using a pair of fiber gratings of different spectral properties. This method is simple and effective. It is promising to become a new spectral technique. The experimental result is also presented.更多还原
