逆滤波器法在能谱测量中的应用

由于传统测量能谱的方法是采用单道、多道的方法，其有一定的分辨时间，并且无法克服相近脉冲的叠加效应，提出了采用逆滤波器法测量能谱的方法。该方法将探测器系统看作具有某一传递函数的线性系统，对探测器系统的输出进行采样，构造系统的离散逆系统，使采样信号通过逆系统，即可取得原始入射粒子的能量与入射时间。仿真结果表明，采用该方法不仅能准确测量原始入射射线的能量，并能测出其入射时间，克服了传统单道、多道进行能谱测量的一些缺点。

Application of inverse filter in energy spectrum measuring

Because the traditional methods of measuring the energy spectrum adopt the single-channel and multiple-channels which results in needing certain distinguish time and cannot solve the problem of superimposed effect of near pluses, a new method adopting the inverse filter to measure energy spec trum is proposed. This method regards the detector system as a linear system that can be described by a transfer function. The output of the detector system is sampled to construct the discrete inverse sys tem of the detector system. So the energy and time of the original incident particles can be obtained af ter the sampling signal gets through the inverse system. Simulation result shows that using this method can test not only the energy of the incident rays, but.also the incident time, which overcomes the de fects of the traditional methods.
