One can trade off complexity in imaging system hardware and strict
system tolerances for complexity in post-detection data processing.
We describe an extreme example in this trade-off space: a coherent
imaging approach that eliminates the imaging system hardware entirely
(except for the detector array), relying on a phase retrieval
algorithm to form the image in a computer. It has applications
ranging from long-range imaging, such as ballistic missile defense,
to microscopy.
