【Abstract】 In this paper the imaging optical characteristics of a tapered defocusing GRIN fi-ber lens are discussed by using the ray path equations.The expressions of the available imagingapertures and view fields for a given fiber lens with the big top or the small top plane towardsthe object are obtained and the relationship between the apertures view fields of the big top andthose of the small top are also given here.更多还原
