High-performance streak camera developed successfully, breaking international monopoly
People are not unfamiliar with the “microscopy” technology. This is a spatial magnification technique for observing the microworld, which can “extend” the spatial resolution of the human eye, while ultra-high-speed imaging is a time magnification technique for observing transient events. “The time resolution of the human eye. The streak camera is the necessary means to realize this microscopic and ultra-fast process detection. It is also the only high-end scientific measurement and diagnostic instrument with both ultra-high time resolution and high spatial resolution. It is also indispensable in the national strategic high-tech research of inertial confinement laser fusion. Or missing diagnostic equipment.
As a very sensitive cutting-edge technology, the international academic research results of streak cameras and the sharing of devices and equipment are very low. Foreign related technologies have imposed strict blockades on China, and strict export controls have also been imposed on streak cameras. The Chinese Academy of Sciences Xi’an Opto-Mechanical Research Institute has established the only streak camera research and development base in China that integrates design, production and testing. At present, eight types of streak cameras have been successfully developed.
On May 22, 2018, the National Key Scientific Research Equipment Project “Development of High-Performance Stripe Cameras” undertaken by Xi’an Opto-Mechanics of the Chinese Academy of Sciences successfully passed the acceptance test, marking that China’s high-performance stripe cameras with independent intellectual property rights have reached the practical level. This achievement breaks the international monopoly in this field and is of great significance to cutting-edge scientific research and major national engineering construction.
