PMT光子计数系统非线性误差测量中数据处理的插值定标方法

Interpolation Method for Measuring-the Nonlinear Error of PMT Photon Counting System

本文给出了用数据处理方法标定PMT(光电信增管)光子计数系统输入、输出非线性关系的原理和实际使用的结果。和通常的强光衰减定标方法相比,该方法不仅简单方便,而且精度较高。

A new method is given to measure the nonlinear error of PMT photon counting system. Compared with the usual method of powerful light declining, it is not only simple and easy, but also of a stisfactory precision.
