However, experimental superiority of deployable systems remains a challenge because of complicated optical nonlinearities, considerable power consumption of analog-to-digital converters (ADCs) for downstream digital processing and vulnerability to noises and system errors<jats:sup>1,6\u20138<\/jats:sup>. Here we propose an all-analog chip combining electronic and light computing (ACCEL). It has a systemic energy efficiency of 74.8 peta-operations per second per watt and a computing speed of 4.6\u2009peta-operations per second (more than 99% implemented by optics), corresponding to more than three and one order of magnitude higher than state-of-the-art computing processors, respectively. After applying diffractive optical computing as an optical encoder for feature extraction, the light-induced photocurrents are directly used for further calculation in an integrated analog computing chip without the requirement of analog-to-digital converters, leading to a low computing latency of 72\u2009ns for each frame. With joint optimizations of optoelectronic computing and adaptive training, ACCEL achieves competitive classification accuracies of 85.5%, 82.0% and 92.6%, respectively, for Fashion-MNIST, 3-class ImageNet classification and time-lapse video recognition task experimentally, while showing superior system robustness in low-light conditions (0.14\u2009fJ\u2009\u03bcm<jats:sup>\u22122<\/jats:sup> each frame). ACCEL can be used across a broad range of applications such as wearable devices, autonomous driving and industrial inspections.<\/jats:p>","DOI":"10.1038\/s41586-023-06558-8","type":"journal-article","created":{"date-parts":[[2023,10,25]],"date-time":"2023-10-25T16:02:11Z","timestamp":1698249731000},"page":"48-57","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":253,"title":["All-analog photoelectronic chip for high-speed vision tasks"],"prefix":"10.1038","volume":"623","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4207-4959","authenticated-orcid":false,"given":"Yitong","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5874-0245","authenticated-orcid":false,"given":"Maimaiti","family":"Nazhamaiti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Han","family":"Xu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1445-8621","authenticated-orcid":false,"given":"Yao","family":"Meng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8850-6839","authenticated-orcid":false,"given":"Tiankuang","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangpu","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingtao","family":"Fan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Wei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3479-1026","authenticated-orcid":false,"given":"Jiamin","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5054-9590","authenticated-orcid":false,"given":"Fei","family":"Qiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3552-0367","authenticated-orcid":false,"given":"Lu","family":"Fang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7043-3061","authenticated-orcid":false,"given":"Qionghai","family":"Dai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,10,25]]},"reference":[{"key":"6558_CR1","doi-asserted-by":"publisher","first-page":"1004","DOI":"10.1126\/science.aat8084","volume":"361","author":"X Lin","year":"2018","unstructured":"Lin, X. et al.
