Imaging & Sensor

Design
The metalens was designed to image a point source to a diffraction-limited spot with working distance 0.5 mm.

OCT image
Structural features of lung tissue are clearly visible, , including moderately scattering epithelium (epi), highly scattering basement membrane (bm), cartilage (car), blood vessel (ves) and alveoli (alv)
Comparison with the state of the art
The ability to tailor the phase at will allows metalenses to be free of spherical aberration and astigmatism
