I guess the task is to design an experiment to test the error between phase inferred from intensity in a digital camera by Huygens-Steiner and a barycentric coordinate map And far more expensive photonic phase sensors.
Is (framerate-1 Hz) a limit, due to the discrete derivative being null for the first n points?
> This means that hard-to-measure optical properties such as amplitudes, phases and correlations—perhaps even these of quantum wave systems—can be deduced from something a lot easier to measure: light intensity.
IDK what happened with wave field cameras like the Lytro. They're possibly useful for face ID, too?

Fortunately this article explained the implications of said breakthrough; "Physicists use a 350-year-old theorem [Huygens-Steiner] to reveal new properties of light waves" https://phys.org/news/2023-08-physicists-year-old-theorem-re... :

"SAR wavefield". There's a thing.
