摘要
本文提出一种处理激光等离子体中含吸收的图像重建方法 ,运用最大熵原理推导出适用于含吸收的重建算法。采用不同的图像实例进行模拟计算 ,计算结果表明采用吸收校正方法的精度明显高于不考虑吸收校正的精度。
A method of image reconstruction with attenuation correction for laser producedplasma is developed in this paper.The principle of maximum entropy is used to derive reconstruction algorithm suited for reconstruction with absorption. The algorithm is used to simulate two images model. The results show that the reconstruction accuracy with attenuation correction is dramatically improved compared to the accuracy without correction.
