传像束光纤在望远瞄准镜中角分辨率的计算方法

Calculate method of angular resolving power of image fiber bundles in telescopic sight

研究了传像束光纤加装在望远瞄准镜中的应用。迄今为止,有关这些方面的研究尚未完善。提出了在望远瞄准镜中传像束光纤角分辨率的定义,建立了角分辨率的数学模型,描述了采用角分辨率来确定在望远瞄准镜中传像束光纤所需截面大小的定量计算方法,结果说明了传像束光纤截面大小与传像束光纤角分辨率、光纤排列及视场等因素的关系。实例计算了一种望远瞄准镜匹配光纤进行传像所得的各项光纤传像系统结构数据,计算数据基本与生产实际相符合。

Application of image fiber bundles in telescopic sight is researched. Up to date, the study of flexible image bundles has not been quantified. The definition of angular resolving power of image fiber bundles in telescopic sight is proposed. One simple mathematic model of angular resolving power is founded. The formula for quantitatively calculating section of image fiber bundles utilizing angular resolving power in telescopic sight is described. The result shows that the relation between the section of image fiber bundles and some factors such as angular resolving power, the arrangement, the field of view, etc. An example on this method is given, and the result accords with the factual production.
