摘要
为了恢复一个复值物函数,本文提出了利用透镜后1f距离,2f距离及3f距离处的强度信息来恢复物函数的振幅分布和位相分布.计算表明,此算法具有广泛的实用性;并能给出很好的收敛结果.
To reconstruct a complex-valued object function, a new algorithm has been proposed. Using the given information of the intensity distributions in If, 2f and 3/ planes behind a lens, the amplitude and phase of a unknown object function can be retrieved. The new algorithm is proved to be practical and also can give an excellent convergent result.
