Wave-field phase retrieval enables full reconstruction of wave-function information. This allows for "omni optics" systems, merging physical hardware with software for versatile imaging applications.

Area of Science:

  • Wave optics
  • Coherent imaging
  • Computational imaging

Background:

  • Wave-field phase retrieval and measurement are mature scientific fields.
  • Reconstruction of complex wave-function provides complete information about wave-field interactions.
  • Current imaging systems are limited by physical hardware components.

Purpose of the Study:

  • To develop the theory for hybrid virtual-physical imaging systems, termed 'omni optics'.
  • To demonstrate the capability of software to emulate diverse optical imaging systems.
  • To showcase the flexibility of 'omni optics' in quantitative imaging applications.

Main Methods:

  • Developing theoretical framework for 'omni optics'.
  • Utilizing wave-field phase retrieval to reconstruct complex wave-functions.
