Transverse Diffraction Technology for Measuring the Characteristics of Fiber Gratings
A new technology for measuring the characteristics of fiber gratings is described. By projecting a beam from a HeNe laser onto the fiber grating transversely and measuring the first Bragg diffraction, the property of fiber gratings can be measured. Based on this technique, the distribution of reflective index of the fiber grating can be obtained.
