The approach is based on the principle that the a pa rticle will form double points on the image plane when the particle is out of fo cus in an optical system with a two pinhole lens.

该方法是当利用双孔透镜成像时，单点粒子在离焦光学成像系统中会形成包含粒子空间信息的两点像，根据粒子像在像平面上的位置和间距可以获取空间粒子的三维空间位置。

"The advantage of our method lies in the smallness, flexibility and precision with which the illuminated area of material can be chosen," Dwyer told nanotechweb.org."Hence, the experimentalist can precisely select the area of material she wants to analyse, and be confident that the surrounding areas are not interfering with her analysis."

对电子显微镜而言，由於物镜工作距离的限制，电子探针与样品常常无法同时被聚焦，因此大部分采用平行式探针的实验都是在探针离焦(out-of-focus)下进行，不幸的是，这种方法会产生如夫奈尔条纹之类多余的图形，因而不如易从绕射图形中精确选出待分析的样品体积。
