We present a framework to estimate the fundamental statistical uncertainty of grating interferometer experiments based on a Monte-Carlo method. Using the framework, we are able to determine the uncertainty of individual measurements as well as suggesting experimental protocols that minimise the statistical uncertainty for given overall exposure times. The method presented here is valid for both X-rays and neutrons and can be generalised for any modulation measurement.
我们提出了一个基于蒙特卡罗方法来估计光栅干涉仪实验基本统计不确定性的框架。使用该框架，我们能够确定单个测量的不确定性，并提出在给定总曝光时间的情况下将统计不确定性降至最低的实验方案。这里提出的方法对X射线和中子均有效，并且可以推广到任何调制测量。
