摘要
对自适应光学中激光导星的基本原理及系统中所需的超窄带滤光技术作了简单的介绍。重点介绍了一些有望应用于激光导星系统上的滤光技术,如:原子共振光学滤光器、双折射滤光器、法拉第反常色散滤光器、法布里-珀罗滤光器等。针对以上滤光技术各自的特点,阐明了它们的基本原理,给出了部分主要参数,并且对各滤光技术的发展现状和不足作了简要阐述。
A short introduction was given about the principles of laser guide star （LGS） in adaptive optics, and the ultra-narrow band filter techniques used in the application. The techniques which would be possible to be used in laser guide star were presented in detail, such as atomic resonance filter, birefringent filter, Faraday anomalous dispersion optical filter and Fabry-Perot filter. Based on the characteristics of each technique, the principles and major parameters were illustrated. Also, the disadvantages and state of each technique were elucidated.
