Analysis of Multiple-Beam Fizeau Fringes Crossing Quasi-D-shaped Optical Fiber

Abstract

Mathematical expression for multiple-beam Fizeau fringes crossing quasi-D-shaped optical fiber is derived. The numerical simulations for the derived equations at different fiber rotations angles have been presented. Experimental validation for the derived equations is verified. Microinterferograms for Fizeau fringes crossing the fiber in transmission is also presented.
