星间激光通信系统要求发射的激光光束具有高度的平行性。光学衍射极限是光束在有限孔径下所能达到的最小发散度,此时波面具有大约0.3l的波面相差。针对星间激光通信波面检测领域,较全面地总结了各类现有检测方法及特点,并给出了一种新颖的互补剪切干涉法的结构与应用实例,最后针对星间激光通信光束波面检测的可行性进行了比较。
Interstellar laser communication system requires the launch of the laser beam with a high degree of parallelism. The optical diffraction limit is the minimum divergence the beam can reach at a finite aperture, at which time the wavefront has a wavefront difference of about 0.3l. Aiming at the field of wavefront detection in the inter-satellite laser communication, various kinds of existing detection methods and characteristics are summarized, and a novel example of the structure and application of the complementary shear interference method is given. Finally, The feasibility of testing was compared.
