Optical Waveguide Fingerprint Recognition Device with Two‐Stage Dual‐Function Gratings (Adv. Mater. Interfaces 10/2023)
Source abstract
Abstract
Optical Fingerprint Recognition In article number 2202361, Weiqiang Lin, Peijin Wu, Zhicheng Ye, and colleagues delicately assembled a series of cooperative sub-wavelength gratings acting as an efficient and ultra-thin light controlling interface based on flexible substrates, by which, the incident beam is sent to the sensing zone via consecutive trapping, splitting, redirecting, and expanding processes. The contrast of fingerprint images is enhanced 11-fold.
