Abstract

The theoretical description of the field reconstructed from an in-line hologram of dispersed media is presented. The intensity distribution in the focal plane of a lens placed behind a hologram is analyzed. It is shown that two overlapped patterns are observing in this plane. The first pattern is entirely in accordance with the small-angle spectrum of radiation scattered by the ensemble of particles, and its view does not depend on the distances between the particles, the hologram, and the lens. The second pattern is made of Fresnel's rings and depends on the distance between the particles and the hologram. A statistical interpretation of the distribution of intensity in the focal plane of a lens is proposed. Experimental results and discussion are presented.

摘要

本文给出了从分散介质的同轴全息图重建场的理论描述。分析了放置在全息图后面的透镜焦平面上的强度分布。结果表明，在该平面上观察到两个重叠的图案。第一个图案完全符合由粒子系综散射的辐射的小角度光谱，其外观不取决于粒子、全息图和透镜之间的距离。第二个图案由菲涅耳环组成，并且取决于粒子与全息图之间的距离。提出了对透镜焦平面上强度分布的统计解释。给出了实验结果和讨论。
