More than 100 Chinese breakthroughs in science and technology are on display this week at the International Optoelectronics Expo in Changchun, northeast China's Jilin Province.
Widely regarded as the cradle of China's optoelectronics industry, the city is hosting over 890 companies and institutions from 23 countries and regions at this year's event.
Running from June 12 to 14, the expo features cutting-edge innovations across more than 10 major sectors, including semiconductors, ultra-precision optics, and commercial aerospace.
Among the exhibitors is a spectral imaging technology company showcasing its latest imaging spectrometer chips, which are already being integrated into the cameras of a leading Chinese smartphone brand to produce more natural and lifelike images.
"This year, we've brought here two upgraded 2MP imaging spectrometer chips, as well as brand-new 5MP and 12MP chips and their modules. Compared with last year, the performance of our products has improved significantly. We've made substantial advances in spectral analysis and image reconstruction, and the overall imaging quality is much better," said Ren Yu, technical director of Jilin Qiushi Spectrum Data Technology Co.,Ltd.
Running alongside the expo, a forum bringing together more than 800 participants from 23 countries has focused on some of the most pressing developments and emerging trends in optical engineering.
Hosting the event is the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), which has built a longstanding reputation as a world leader in ultra-precision optical manufacturing.
"I've been here many times already. China is active in many fields. What in CIOMP impressed me a lot is the high precision mirrors they are making. So that's really a specialty of them. So that's very impressive for space applications," said Paul Urbach, scientific director of Dutch Optics Center.
"It's clear the industry that there is in China, we don't have that in Argentina at all. I haven't seen this in another country; also like I've been many times in US for cooperations, I didn't see this kind of growing in other part of the world. Actually I'm pretty impressed," said Maria Gabriela Capeluto, professor of Physics at University of Buenos Aires.
