Microtomography of the polarization-maintaining fiber by digital holography
DH is used to record complex transmitted fields under various angles of incidence. FDT algorithm is applied to reconstruct the 3-D RI distribution of PMF. Geometric parameters can be obtained from RI map by the edge detection algorithm. Experimental results prove the feasibility of Microtomography of PMF by DH.
