关于光学系统中空间关联函数的位相恢复问题

摘要: 本文把文献[1]中提出的振幅和位相恢复问题的一般表述用于处理空间关联函数位相的恢复问题,类似于文献[1],得到了一组确定位相的方程,用该方程组和迭代求解法,可以求解空间关联函数的位相,但本文不假定传输矩阵R是幺正的。可以证明,如果R是幺正矩阵,在相干极限下,本文的方程组回到文献[1]中的相应方程。

Abstract: In this paper, we generalize the method proposed in [1] to solve the phase retrieval problem of spatial correlation functions in optical systems. A set of equations for determining the phase of the correlation functions is given. Using these equations and the iteration computing method, the phase of correlation functions can be determined. It can be shown that, if the transmission matrix K is unitary, in the coherent limit, the equations derived in this paper turn out to be that obtained in [1].
