This project, led by Prof. Xu Zhihai from COSE, won the first prize of Sci & Tech Progress Award of MOE. The research team proposed a series of highly reliable and ultra-small CMOS optical camera design and development methods suitable for the Earth Moon space environment, achieved independent innovation and technological breakthroughs, and formed the Chang'e series optical observation camera technology with independent intellectual property rights. All cameras developed by the team have successively been applied in the national lunar exploration projects Chang'e-2, to Chang'e-5 missions, and have created three international firsts, also have created three firsts in China, and have made important contributions to the successful completion of China's lunar exploration project.
