摘要

要提高无透镜光学的效率并扩大其应用范围，就必须提高其测量光场的可靠性。本文研究了相位物体（即透镜）产生的复杂光场。结果表明，使用两个或更多距离物体不同距离的强度分布测量值，可以进行可靠的相位重建。本文以一个圆形光阑和位于其后面的透镜组合为对象。

Reconstruction of the Complex Field of an Exit Wave of a Phase Object from Measurements at Different Distances

Improving the efficiency and expanding the scope of application of lensless optics require increasing its reliability in measuring light fields. The paper examines the complex field generated by a phase object, i.e., a lens. It is shown that reliable phase reconstruction is possible using two or more measurements of the intensity distribution at different distances from the object. A combination of a circular diaphragm and a lens located behind it is used as an object.
