| Abstract: | 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). |

| Keywords: | GRINT imaging optical fiber overlapping rate resolution illumination effective numerical aperture |
