Nondestructive measurement for arbitrary RIP distribution of optical fiber preforms

A nondestructive method is presented to determine simultaneously the refractive index profile and the cross section geometry of optical fiber preforms. An improved formula for calculating the optical path length from the deflection function is derived. The preform is rotated through 180/spl deg/ and...
