中性粒子气体探测器视差的离线校正

Off line Parallax Correction for Neutral Particle Gas Detectors

Patrick Van Esch

摘要:

在中性粒子气体检测器中,由从点状源(诸如散射样本)发出的径向粒子轨迹在检测平面或线上的垂直投影所导致的视差误差可以显著地破坏检测器的表观角分辨率。然而,正如我们将展示的,信息并没有丢失。我们提出了一个离线的数据处理,以恢复尽可能多的原始散射信息的情况下,一维视差效应。视差的可逆性来自这种效应的代数结构,这与本质上不可逆的分辨率损失不同。有限分辨率和视差之间的相互作用使问题复杂化,但这是可以解决的。

英文摘要:

In a neutral particle gas detector, the parallax error resulting from the perpendicular projection on the detection plane or wire of the radial particle trajectories emanating from a point like source (such as a scattering sample) can significantly spoil the apparent angular resolution of the detector. However, as we will show, the information is not lost. We propose an off line data treatment to restore as much as possible the original scattering information in the case of a one-dimensional parallax effect. The reversibility of parallax follows from the algebraic structure of this effect, which is different from the resolution loss which is essentially irreversible. The interplay between finite resolution and parallax complicates the issue, but this can be resolved.
