论文摘要
受到一致的冷冻波的概念的启发，本文引入了其部分的一个可能的理论框架，它是一种冷冻的空间连贯性，其中通过将部分相干轴的光场建立了所需的两点相关结构，该结构是通过将部分连贯的零级Bessel Bessel束在繁殖轴上创建的。结果表明，可以根据二维傅立叶序列给出跨光谱密度的描述，类似于相干冷冻波的一维方法。形式主义应用于部分连贯场的设计，仅当传播轴中的一对属于预定的有限范围和该范围之外的高度不连贯性时，才具有高度连贯的。
Inspired by the concept of coherent frozen waves, this paper introduces one possible theoretical framework of its partially coherent version, a frozen spatial coherence, in which a desired two-point correlation structure of an optical field is created on the propagation axis by superposing partially coherent zero-order Bessel beams. It is shown that the cross-spectral density can be given a description in terms of a two-dimensional Fourier series, analogous to the one-dimensional approach of coherent frozen waves. The formalism is applied to the design of a partially coherent field which is highly coherent only if the pair of points in the propagation axis belong to a predetermined and finite range and highly incoherent outside that range.
