China has become the third country to master the solar MCAO technology.
recently, with the assistance of the Yunnan Observatory of the Chinese Academy of Sciences, the solar high-resolution optical imaging research team led by raochanghui, a researcher at the Institute of optoelectronic technology of the Chinese Academy of Sciences, successfully broke through the key technology of the next generation adaptive optics - Multilayer conjugate adaptive optics (MCAO). The success of this experiment marks a major breakthrough in the field of next-generation adaptive optics technology, making China the third country to master solar MCAO technology after the United States and Germany
researchers used the solar MCAO system principle prototype developed by them to dock with the 1-meter new vacuum solar telescope of Yunnan Observatory, and successfully realized the large field of view closed-loop correction imaging observation of the solar active area. For the first time in China, MCAO technology was used to obtain a large field of view high-resolution real-time image of the solar active area
the development and application of multilayer conjugate adaptive optics technology will help solar physicists see clearer, finer and more dynamic solar activities, deepen human understanding of stars and even the universe. This is the best way to make spacecraft lighter, and will also provide strong data support for space environment monitoring and space weather forecasting
researchers revealed that a special MCAO system will be equipped for the 1-meter new vacuum solar telescope of Yunnan Observatory in the next five years, so as to realize the successful application of this technology
it is understood that accurate early warning and prediction of solar activities can avoid the impact of disastrous space weather on human normal activities to the greatest extent and ensure the safety of space engineering. In order to study the dynamic origin of solar activity and realize accurate space environment monitoring and space weather prediction, it is necessary to obtain large field of view and high-resolution observation data of solar activity area. The ground-based large aperture solar telescope equipped with adaptive optics system is the main method to carry out high-resolution solar observation, but it is an important means for good detection during assembly and after the event. The traditional adaptive optics system can not directly meet the needs of high-resolution observation of the entire solar activity region. In order to solve the problem of small field faced by traditional adaptive light schools, scientists have developed MCAO technology, which has made great progress in recent years
accurate early warning and prediction of solar activity can avoid the impact of disastrous space weather on human beings' regular downward movement of the beam caused by the rotation of the ball screw driven by the proper servo mechanism. However, the traditional adaptive optical system can not directly meet the needs of high-resolution observation of the entire Taiyang activity area. The use of MCAO technology can help to obtain real-time images with high resolution in large field of view of Yang active area, which can be weakened by plastic deformation, and will provide strong data support for space environment monitoring and space weather prediction
