Utilizing the theory of di raction of light, a hologram can be used to reconstruct three-dimensional (3D) images [39]. With this advantage, holography can be used to perform simultaneous imaging of multidimensional information, such as 3D structure, dynamics, quantitative phase, 4 R. Hyder, Z. Cai, M. Asif.

The resulting inverse problem, known as holographic phase retrieval, is well-known to have improved problem conditioning relative to the original. This innovation, i.e. Holographic CDI, becomes crucial at the nanoscale, where imaging specimens such as viruses, proteins, and crystals require low-photon measurements.

Holographic phase retrieval

A general mathematical framework and recovery algorithm is presented for the holographic phase retrieval problem. In this problem, which arises in holographic coherent diffraction imaging, a "reference" portion of the signal to be recovered via phase retrieval is a priori known from experimental design.
