摘要
讨论了概率成像方法的一个不足,提出一种:采用电位的二次导数进行成像的方法,通过算例分析证明,这个新的成像公式的分辨能力更高一些,而且能够提高对小强度电荷的定位能力。
A shortage of approach of probability tomography is discussed in detail, and a new formula about second derivative of portontial is given. Examples show that this formula has higher resolving power, which can given a better of lower quantity of charge.
