How can we measure the Refractive Index of a 2 m long
optical fiber?
Answer / sreenesh shashidharan
A novel transmitted-light differential interference
contrast (DIC) system is used for nondestructive
measurement of the refractive-index profile (RIP) of an
optical fiber. By means of this system the phase of a
measured light beam can be modulated with an analyzer, and
the phase distribution of a fiber is obtained by
calculation of the various interference patterns. The
measurement theory and structure and some typical
applications of this system are demonstrated. The results
of measuring RIPs in graded-index fiber are presented. Both
the experimental results and theoretical analysis show that
the system takes the advantage of high index resolution and
of sufficient measurement accuracy for measuring the
refractive index of the optical fiber. The system has
strong ability to overcome environmental disturbance
because of its common-path design. Moreover, one can use
the system to measure the RIP along the fiber axis and
acquire an image of the three-dimensional RIP of the fiber.
