Fig.2 Full-color neural array imaging system compared with a conventional compound lens camera. (a) Prototype of neural array imaging system. (b) An optical microscope image of the neural array mapping metalens. Scale bar, 250 µm. (c) Scanning electron microscope of the neural array mapping metalens. Scale bar, 300 nm. (d) Point spread function of neural array mapping metalens. (e) Modulation transfer functions of neural array imaging system metalens. (f) Edmund compound lens. (g) Images captured by the Edmund compound lens camera when imaging a display screen, indoor scenes, outdoor settings, and a 1951 USAF resolution test chart. (h) The neural array mapping. (i) Images captured by the neural array imaging system under the same conditions. (j) The sequence of six frames captured during real-time video-rate imaging, alongside their respective times.
