摘要
梯度折射率(GRIN)成象光纤的光学特性与光纤长度的关系是光纤应用中一个重要问题。本文从理治与测量方面说明光纤长度与光纤光学特性如:物象距,最大半视场角、最大场高、有效数值孔径、照度分布以及MTF的关系。
The relationship of its imaging characteristic with the length is of importancewhen the gradient index (GRIN) imaging optical fiber is used in image systems.Through theoretical deduction and interpretation of the experimental data, thispaper elucidates the dependence of the length of the optical fiber on such opti-cal parameters as image and object distance, maximum half width of view field,maximum field height, effective numerical aperture, distribution of illumina-tion, and modulated transfer function (MTF).
