Abstract

The exact determination of the modulation transfer function (MTF) of a physical system is a persistent problem. We present a practical method of measuring numerically the MTF of linear solid-state x-ray-sensitive detectors. The method is based on the use of edge techniques and allows us to obtain the MTF of a linear detector from its edge-spread function (ESF). ESF measurement techniques are discussed in detail, and calculation of the corresponding MTF's are shown.

摘要

精确测定物理系统的调制传递函数（MTF）一直是个难题。我们提出了一种通过数值方法测量线性固态X射线敏感探测器MTF的实用方法。该方法基于边缘技术，使我们能够从线性探测器的边缘扩展函数（ESF）中获取其MTF。详细讨论了ESF测量技术，并展示了相应MTF的计算方法。
