Abstract
An endoscopic imaging device (e.g., a catheter) comprises a light-transmitting tubing, at least one optical fiber disposed in the light-transmitting tubing, and at least one metalens. The metalens is optically coupled to the optical fiber and is configured to focus light from the optical fiber, through the light-transmitting tubing, and to a target point located outside of the light-transmitting tubing. The metalens includes a plurality of nanostructures. The nanostructures define a phase profile that corrects astigmatism caused by the light-transmitting tubing.
