摘要

针对光中子成像中的模糊图像还原问题

研究了模糊来源

建立了一种物理数学模型。在此基础上

分别使用非约束条件下以及约束条件下的迭代算法

对数学模型进行求解。模拟及实验数据反解结果表明

约束条件下的反解算法能有效地消除成像中的模糊重叠现象

有利于更加清晰准确地判断被探测物的性质。

Abstract

To improve imaging performance of photo-neutron explosive detection system

reasons of spatial resolution deterioration is investigated

and physical and mathematical model are established.The function is solved using iterative algorithm under constraints and non-constraints condition

respectively.The simulation and experiment results show that the method with constraints can improve effectively accuracy of the explosives detection system by eliminating the pixel overlapping.
