摘要：The conventional optical system design employs combinations of different lenses to combat aberrations, which usually leads to considerable volume and weight. In this Letter, a tailored design scheme that exploits state-of-the-art digital aberration correction algorithms in addition to traditional optics design is investigated. In particular, the proposed method is applied to the design of refractive telescopes by shifting the burden of correcting chromatic aberrations to software. By enforcing cross-channel information transfer in a post-processing step, the uncorrected chromatic aberrations are well-mitigated. Accordingly, a telescope of F-8, 1400 mm focal length, and 0.14° field of view is designed with only two lens elements. The image quality of the designed telescope is evaluated by comparing it to the equivalent designs with multiple lenses in a traditional optical design manner, which validates the effectiveness of our design scheme.

摘要：濒海战斗舰(Littoral combat Ship,LCS)是美国海军下一代水面战舰的第一种设计。作为在濒海区域(靠近海岸)作战的相对小型水面船只,LCS比海军的导弹驱逐舰更小,与国际上所指的护卫舰相仿。单数舰'自由'级采用常规单体设计,而双数舰'独立'级则采用三体设计。'科罗纳多'号是'独立'级的第2艘,是整个濒海战斗舰项目的第4艘,2012年1月下水,2014年4月服役,以加利福尼亚州圣地亚哥为母港。2016年7月19日在'环太-2016'军演中,该舰首次在前甲板试射'鱼叉'反舰导弹。
