此后，将考虑对条纹插值，算出网格点位置的应变或位移的问题。

After this, the problem will be considered of how to interpolate fringes. so as to compute strain or displacements at mesh point locations.

由于背景场是由解析公式给出的，所以可以将场源放置在数值网格的任意位置，不一定非得在网格点上。

Since the background field can be computed analytically, the source can be located at any point that does not need to be a grid point.
