Abstract：
 The invention relates to a fiber grating which can realize any target response, which belongs to fiber communication, optical sensor and other relative light signal processing fields. The product is a fiber grating of sampling structure realized with phase model scanning method; the period and phase function of the initial end of the fiber grating, As, Phi s (z) and A s (z) are period, phase function and apodization function of any given fiber grating initial end. And it can acquires distance Zk from the K ultraviolet exposure position to the sample fiber grating initial end and the amplitude Ak of refraction rate modulation leaded in at the Zk. The character of the invention is: its reflection spectrum has multi-channel type, and some special reflection peak in them has the demanded target reflection response, or has the character of target phase shift.
