On July 25, China's Long March 4B carrier rocket ignited and lifted off at the Taiyuan Satellite Launch Center. It successfully sent the Ziyuan-3 03 satellite into a predetermined orbit and launched the Lobster Eye X-ray detection satellite on board. The bionic lobster eye focusing lens developed by the Fiberglass Institute of ZGJC Composites Technology Group was first equipped and applied to help China's deep space exploration industry.
The lobster eye X-ray detector carried by the satellite was jointly developed by China Aerospace Corporation, Nanjing University and ZGJC for 5 years. It will be the first lobster eye X-ray detector in the world to work in orbit and obtain data. The detector mainly carries out the verification of X-ray large field of view focusing imaging technology, as well as several important space X-ray detection experiments, especially the deep detection of dark matter signals in the X-ray energy range. In the future, it will be provided by Nanjing University and the University of Hong Kong. High-precision space scientific exploration data.
The biomimetic lobster eye focusing lens is made up of micron-level square hole channels arranged regularly. It uses the reflection of the inner wall of the hole to realize grazing incidence imaging detection of soft X-ray spectrum photons. It is inspired by the unique structural form of lobster eyes in the biological world. The advantages of large field of view, high resolution, light and small size, and easy integration are the "eyes" of the lobster eye X-ray detection detector.
After years of research and development, the project team has successively overcome key technologies such as basic glass material design and preparation, high-precision micron-level square hole channel preparation, and large curvature radius blank slab forming. The performance meets the design index requirements, and has passed ground test verification and successfully achieved The carrying application provides key material support for the development of the new lobster eye X-ray detector.
The successful application of the bionic lobster eye focusing lens and its micro-structure bionic lobster eye micro-hole lens is the high-stability glass tube for the fiberglass institute and the atomic clock during the "13th Five-Year Plan" period, the composite micro-hole collimating glass material, and the optical fiber for the star sensor After the strobe, another new material developed for aerospace applications.
ZGJC will further in-depth cooperation and intensive research with user units, continuously improve material performance, quality stability and supporting capabilities, and make new and greater contributions to my country's space science, deep space exploration and other fields. At the same time, the General Hospital will further increase the transformation of scientific and technological achievements, and accelerate the development of civil products such as flexible optical fiber image bundles, radiation-resistant optical fiber panels, all-solid inorganic electrochromic glass, etc., for high-end medical equipment and green energy-saving buildings. , High-speed rail, aircraft, etc. provide basic key material support, and promote high-quality development with technological innovation.
