中科院光电技术研究所不久前研制成功“21单元自适应光学星体目标成像补偿系统”,它使我国成为继美国、德国之后,第三个实现星体目标自适应光学校正的国家。由于大气湍流等动态干扰影响,象斑能量分散而且不断漂移,在地面上通过大型望远镜观察远方目标,分辨能力远达不到光学系统的理论值。这是困扰光学界的一个老问题。现代科技自适应光学的出现,为克服这一障碍提供了解决办法。自适应光学依靠实时波前传感器、高速
Recently, the Institute of Optics and Electronics of the Chinese Academy of Sciences (CAS) successfully developed “21-Unit Adaptive Optical Astral Target Imaging Compensation System”, making China the third country to achieve adaptive optical correction of astral targets after the United States and Germany. Due to the dynamic disturbance such as atmospheric turbulence, the energy of the image patch is dispersed and constantly drifting, the distant target can be observed through the large telescope on the ground, the resolving power far falls short of the theoretical value of the optical system. This is an old problem plaguing the optical community. The emergence of modern science and technology adaptive optics provides a solution to overcome this obstacle. Adaptive optics rely on real-time wavefront sensors, high-speed
