Three-Dimensional Structure from Single Two-Dimensional Diffraction Intensity Measurement

Conventional three-dimensional (3D) imaging methods require multiple measurements of the sample in different orientation or scanning. When is probed with coherent waves, a single two-dimensional (2D) intensity measurement sufficient as it contains all information 3D distribution. We show method that allows reconstruction distribution from 2D measurement, at z-resolution exceeding classical limit. The can be practical for radiation-sensitive materials, where experimental setup only one measurement.
