| الوصف: | Quantitative phase imaging (QPI) recovers the exact wavefront of light from the intensity measured by a camera. Topographical maps of translucent microscopic bodies can be extracted from these quantified phase shifts. We demonstrate quantitative phase imaging at the tip of an optical fiber endoscope with a chromatic silicon nitride metalens. Our method leverages spectral multiplexing to recover phase from multiple defocus planes in a single capture. The half millimeter wide metalens shows phase imaging capability with a 280 field of view and 0.1{\lambda} sensitivity in experiments with an endoscopic fiber bundle. Since the spectral functionality is encoded directly in the imaging lens, no additional filters are needed. Key limitations in the scaling of a phase imaging system, such as multiple acquisition, interferometric alignment or mechanical scanning are completely mitigated in the proposed scheme |
