1. A system for imaging an object, said system comprising: a light source configured to emit light having a predetermined wavelength towards the object; a metalens comprising a metallic film having a plurality of slits defined therethrough, the plurality of slits having a width a and a periodicity d that are both less than the predetermined wavelength, wherein the object is positioned between said light source and said metalens; a detector configured to acquire measurements indicative of light transmitted through said metalens; and a computing device communicatively coupled to said detector and configured to reconstruct an image of the object based on the acquired measurements.
