Furthermore, the metasurface doublet lens is telecentric in the image space, and light is incident on the image sensor with the uniform angular distribution (Supplementary Fig. 5), and thus removing the need for the variable incident angle correction in the image sensor. Correcting chromatic ...
Telecentric imaging was introduced for single-camera, 2D measurement applications as an object appears at the same size irrespective of its position along the optical axis (Fig. 3) [12]. It employs a lens with aperture matching the field of view, and Fresnel lenses enable large, metre-scale ...
