Design of four-mirror reflective anastigmat optic system[J]. 引用該論文 丁學(xué)專

Anastigmatic lens: Photographic lens corrected for astigmatism as well as other distortions. 消像差透鏡:消除縱橫像差和其他畸變的攝影用透鏡。

Results There were 28 cases with anastigmatic recurrence, the signs on CT were mass a rounding anastigmatic. 查閱病例，了解切除范圍，探討術(shù)后復(fù)發(fā)的原因。結(jié)果吻合口復(fù)發(fā)28例，在CT片上表現(xiàn)為吻合口區(qū)不規(guī)則腫塊影；

Three-mirror anastigmat can not meet the requirement of reducing weight and compacting size in some circumstances. 常見的離軸三反系統(tǒng)已不能滿足系統(tǒng)小型化、輕量化的要求。

A unobstructed four-mirror anastigmat system was proposed, which was modified based on three-mirror anastigmat and had compacter structure. 介紹了一種無中心遮攔的離軸四反射鏡系統(tǒng)，由離軸三反系統(tǒng)改進(jìn)而成，結(jié)構(gòu)更加緊湊。
