Abstract

A system for identifying objects in images is provided. The system may include an optical front end and a digital back end. The optical front end includes a metalens that duplicates a received image into multiple images, and a metasurface that receives the duplicate images and outputs a feature map based on the received images. The feature map may be equivalent to the computationally expensive convolution operations previously performed by a neural network. The feature map is provided to the digital back end, which uses a neural network to classify the object. Because the feature map included the convolution operations, the digital back end can classify the object more quickly and using fewer computing resources than previous systems.
