摘要
In article number 1900126, Xu Liu, Qing Yang, and co‐workers present a waveguide chip design that permits label‐free superresolution imaging. The method captures all sample spatial frequencies over a large bandwidth, permitting artifact‐free reconstruction. Two‐dimensional sample structures are imaged without distortion and reconstructed over large field of views at sub‐wavelength resolution. The results match well with data obtained via SEM and AFM imaging.
