| 摘 要： | 针对目前国内市场遥控武器站遥控枪塔的CCD瞄准镜不能在整个焦距范围内任意视场进行瞄准射击的问题,设计了一个前置分划板连续变焦CCD瞄准镜光学系统.它不同于一般的变焦系统,该系统采用补偿组线性运动,变倍组凸轮曲线运动的变焦方式来保证像面稳定.系统变焦比为5:1,在一定焦距范围内实现连续变焦,并且通过采用分划板前置的方式,... |

| Abstract: | To aim at domestic CCD sighting piece of gun tower of the telecontrol armament station is incapable of taking aim at all field of vision at the whole focus range,a CCD sighting piece of prepositive sight leaf graduation optics system in continuous zoom is designed,which differs from the common zoom system.This system moves in compensating linearity,zoom group moves in cam curve to ensure the imaging plane to level off.Zoom proportion is 5∶1.It can zoom continuously in the length focus range.It also achives in taking aim at all field of vision at the whole focous range,the accuracy of take aim at is to stabilize dependable.The field curvature is emended by locale lense,the quality of the image is nice.To apply theory of dynamic optics,it indicates the moving curve resolution type of the zoom group versus the compensating group.The structure is compact,zoom distance is short and zoom track is smoothness,The image plane is tranquilization. |
| Keywords: | optical design preposititive sight scale dynamic optics compensation moves in linearity continuous zoom |
