Starting from the ray path equation, object-image relationships are found and used to determine the equivalent focal length and the principal planes of tapered GRIN fiber. These equation reduce to the known formulas when m = 0 (that is, for a cylindrical GRIN fiber). The aperture of tapered GRIN fiber is discussed in this paper and the photographs of the image are also included.
