| 摘 要： | 对于自适应光学系统,液晶波前校正器是一个非常有前景的波前校正器件。传统的向列相液晶波前校正器的主要缺点是偏振依赖和工作波段窄。采用了基于偏振分束器的开环光路设计和优化的能量分割方法来分别解决上述问题。结果显示,开环光路非常适合于液晶波前校正器,且新颖的能量分割方法显著提高了液晶自适应光学系统的探测能力。

| Abstract: | Liquid crystal wavefront corrector (LCWFC) is one of the most attractive wavefront correction devices for adaptive optics system. The main disadvantages for conventional nematic LCWFC are polarization dependence and narrow working waveband. A polarized beam splitter (PBS) based open loop optical design and an optimized energy splitting method was used to overcome these problems respectively. The results indicate that the open loop configuration is suitable for LCWFC and the novel energy splitting method can significantly improve the detection capability of the liquid crystal adaptive optics system. |
