Here is a paper from 2014 on making one computational microscope using a >> raspberry pi w/ pi camera and a 3d printer: >> https://pmc.ncbi.nlm.nih.gov/articles/PMC4169052/ >> It has a resolution of around 600 nm but also provides per-pixel angular >> photon phase. It’s only about as big as a raspberry pi. >> The FPM approach makes it easy to correct for lens problems, alignment >> problems, manufacturing errors etc, because of how simple the iterative >> process for fitting the model of the object is. >> > > Oops that’s a different paper >
This is the paper matching my description. It is from 2019. https://www.nature.com/articles/s41598-019-43845-9
