- Description
- Holography allows encoding amplitude and phase information in an interference pattern. With the advance of digital detectors and computing technology, it was possible to record the holograms digitally and process them afterwards. This enables direct access to the quantitative phase information that can be used for phase imaging or to measure shape and deformation of large or small samples. With the further advance of computing power and processing time, other more computationally demanding methods for retrieving the phase have been developed at the benefit of not requiring a separate reference wave and hence enabling a more environmentally robust setup. This presentation describes and compares phase retrieval methods using holographic (with reference) and reference-free setups.
