| 摘 要： | 叙述在70mm大画幅同步高速摄影机大视场长焦距光学系统中,首次采用折反式结构的光学系统。成功地解决了由于视场大而引起中心拦光大,使轴外像质MIF下降过快的问题。做到该光学系统总长度∑L<0.6f′,轴外MTF在N=301p/mm时,MTF>0.4,达到了使用要求。

RESEARCH OF OPTICAL SYSTEM WITH WIDE FIELD OF VIEW AND LONG FOCUS FOR 70mm HIGHT SPEED CAMERA |
| |
| Abstract: | A WFOV long focus optical system of 70mm large frame hight speed camera is discussed. The optical system of the catadioptric structure is used in it for the first time. The problem that the off axis image quality decreased too quick because of the large central stop caused by the wide FOV is successfully solved. The whole length of optical system ∑L0.4 at N=30lp/mm are achieved. |

| Keywords: | large frame catadioptric optical system central obscuation |
