主　　题：object identification three-dimensional reconstruction optical computing metasurface 

摘      要：Object identification and three-dimensional reconstruction techniques are always attractive research interests in machine vision,virtual reality,augmented reality,and biomedical *** computing metasurface,as a two-dimensional artificial design component,has displayed the supernormal character of controlling phase,amplitude,polarization,and frequency distributions of the light beam,capable of performing mathematical operations on the input light ***,we propose and demonstrate an all-optical object identification technique based on optical computing metasurface,and apply it to 3D *** traditional mechanisms,this scheme reduces memory consumption in the processing of the contour surface *** identification and reconstruction of experimental results from high-contrast and low-contrast objects agree well with the real *** exploration of the all-optical object identification and 3D reconstruction techniques provides potential applications of high efficiencies,low consumption,and compact systems.
