BEIJING — A Chinese research team from Tsinghua University has unveiled a revolutionary spectroscopic imaging chip, RAFAEL, that could transform how humanity observes the universe.<\/p>\n
Published in Nature this week, the breakthrough resolves the long-standing trade-off between spectral resolution and throughput\/efficiency, enabling high-performance yet easily integrable snapshot spectroscopy.<\/p>\n
Spectroscopy is a fundamental tool for revealing the physical structures and chemical compositions of matter, underpinning discoveries across physics, chemistry, astronomy and life sciences.<\/p>\n
However, traditional instruments have long faced an inherent challenge in achieving both ultra-high resolution and high throughput. Enhancing one typically requires compromising the other, creating a seemingly insurmountable barrier to achieving both simultaneously.<\/p>\n
RAFAEL, with its Chinese name “Yuheng,” breaks this limitation through integrated and reconfigurable lithium-niobate photonics, enabling each pixel in the sensor to capture complete spectral data with ultra-high optical transmittance.<\/p>\n
The chip achieves snapshot spectroscopy with a 10-megapixel spatial resolution and a spectral precision of 0.05 nanometers across visible to near-infrared wavelengths.<\/p>\n
In an on-sky demonstration, RAFAEL captured spectra in that precision of up to 5,600 stars in a single exposure, representing more than a hundredfold improvement in observational efficiency over world-class astronomical spectrometers.<\/p>\n
Compact yet powerful, the chip could unlock new insights into the most enigmatic phenomena in the cosmos while advancing research from materials science to astrophysics, said Fang Lu, a professor at Tsinghua and corresponding author of the paper.<\/p>\n
“Yuheng” derives its name from the fifth star of the Big Dipper, once used by ancient Chinese astronomers to calibrate celestial movements, embodying precision and balance.<\/p>\n
Building on this legacy, the chip aims to establish a new stable benchmark for human astronomical observation of light and the universe, Fang said.<\/p>\n","protected":false},"excerpt":{"rendered":"BEIJING — A Chinese research team from Tsinghua University has unveiled a revolutionary spectroscopic imaging chip, RAFAEL, that…\n","protected":false},"author":2,"featured_media":89145,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[607,111,139,69,147],"class_list":{"0":"post-89144","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-science","8":"tag-china","9":"tag-new-zealand","10":"tag-newzealand","11":"tag-nz","12":"tag-science"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/89144","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/comments?post=89144"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/posts\/89144\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media\/89145"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/media?parent=89144"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/categories?post=89144"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/nz\/wp-json\/wp\/v2\/tags?post=89144"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
