| 摘 要： | 自适应光学系统应用于天文观测时应满足一些技术要求，其中的关键技术之一是自适应光学系统为了对畸变的光波进行采样，需要在其很小的等晕角内有足够的信标强度。激光引导星，即人造信标，就是解决这种问题的方法之一。特别是在观测天文暗目标时，其自身的光强度不能为有探测提供信息，激光引导星就蛤得非常重要。根据国际上的最新进展对激光引导星技术给予了介绍。重点介绍了激光引导星的局限性，对近几年提出的对激光引导星可能的

| Abstract: | Adaptive optical systems should satisfy some technical requirements when they are being applied to astronomical observation. One of the key issues is an enough intensity of beacon required to sample the wavefront distortions in a small isoplanatic angle for an adaptive optical system. Laser guide star, an artificial beacon, is one of the solutions for this issue. Especially for astronomical observation of a faint object, the wavefront sensor can not sample its light. In this case, the laser guide stars are very important. According to the latest progress in the world, the laser guide star technique is introduced, and emphatically for the limitations of the laser guides star. A brief introduction for the proposed possible techniques to determine the tilt of laser guide stars is also given. |
