Chip-scale metamicroscope for high-performance imaging

https://phys.org/news/2022-07-chip-scale-metamicroscope-high-performance-imaging.html

"co-and-cross-multiplexed metalens array and embedded polarizer... integrating chip-scale CMOS sensor... wide FOV and large DOF microscopy technique. Significantly high performances with 4×4-mm2 FOV, 1.74-μm resolution (limited by CMOS pixel size), and ~200-μm DOF (450-510-nm wavelength range). FOV 5 to 7 times that of traditional microscope with same resolution... demonstrated the outstanding microscopy performance by imaging a large number of bio-specimens"
