We nest an iterative, unapproximated compressed sensing reconstruction algorithm into our end-to-end optimization pipeline, resulting in an interpretable, data-efficient method for maximally leveraging metaoptics to exploit object sparsity. We apply our framework to super-resolution imaging and high-resolution depth imaging with a phase-change material. In both situations, our end-to-end framework computationally discovers optimal metasurface structures for compressed sensing recovery, automatically balancing a number of complicated design considerations to select an imaging measurement matrix from a complex, physically constrained manifold with millions ofdimensions. The optimized metasurface imaging systems are robust to noise, significantly improving over random scattering surfaces and approaching the ideal compressed sensing performance of a Gaussian matrix, showing how a physical metasurface system can demonstrably approach the mathematical limits of compressed sensing.","lang":"eng"}],"doi":"10.1021/acsphotonics.4c00259","publication_identifier":{"eissn":["2330-4022"]},"OA_place":"repository","date_published":"2024-04-23T00:00:00Z","arxiv":1,"year":"2024","type":"journal_article","title":"End-to-end optimization of metasurfaces for imaging with compressed sensing","publication":"ACS Photonics","language":[{"iso":"eng"}],"scopus_import":"1","quality_controlled":"1","date_created":"2026-04-09T09:10:41Z","status":"public","user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","citation":{"chicago":"Arya, Gaurav, William F.
