Abstract

In order to obtain the reflective spectrum of fiber grating which has high resolution, an algorithm of the reflective spectrum was pesented, which can realize high scaning's frequency and high resolution synchronous, that is to say, it can deal with the obtained reflective spectrum by image interpolation algorithm using many-knot spline function. It can be shown that inserted reflective spectrum's resolution increase 2 times. The experimental results proved that it has certain instructional significance by image interpolation algorithm using many-knot spline function deal with the reflective spectrum of fiber grating.
