Fig. 2 Wide-FOV imaging and bioimaging results of the trichannel metalens. (a) Imaging results of Group 6 of the test target in different channels at normal incidence. The FOV zones marked by solid circles are 20°. The distance between the metalens and the object is 645 μm. (b) The normalized intensity distribution along the corresponding dashed line in (a). (c) Bioimaging results of (top) Spirogyra conjugation and (bottom) Volvox cells. Left panel: optical microscope images. Right panel: imaging results of the portion marked by the red box in the left panel using the polarization-encoded trichannel metalens.
