An approach to improve the image quality by aperture synthesis in generalized phase-shifting interferometry is proposed.The aperture of the holographic system is enlarged by increasing the recording area to receive a more diffusive spectrum by moving a singular CCD.The sub-object wave fronts are combined with the index of their intensities.This method can avoid the negative effect of environmental disturbance and improve the synthesis efficiency by hundreds of times.The optical experiments have shown that it is simple and robust to stitch the complex object wave front accurately and to improve the imaging quality greatly,especially for the recording of large scale objects.

导 读:  交际语境要素是语文阅读课堂“问题链”设计的学理依据。从名师肖培东的课堂实例来看,可从“作者”“读者”“话题”“文体”这四个方面入手,观照语篇标题,激活审辩思维;凸显学生主体,呵护精神成长;立足单元主题,强化育人价值;紧扣文体特质,提升阅读品质。  教师倘若忽视对“问题链”的精心设计,势必会落入阅读教学琐碎低效的窘境。对此,肖培东老师曾说:“好的课一定是靠好的问题来推动的。”别致考究的“
