      Two additional notes:

      1. In the 1990s, in _Applied Optics_, I read about creating diffractive lenses by shining coherent light through an optical system, and placing holographic film at a midpoint in the system, far from any focal point. The ‚hologram (maybe a Gabor hologram) created a corrected optical system, at the one wavelength of light that had been used.
      2. I first came across this article as a reference in the Phys Org summary, „New image sensor breaks optical limits“ https://phys.org/news/2025-12-image-sensor-optical-limits.html
