Fiber optic connectors for connecting devices in optical fiber communication plays a vital role for the fiber-optic system connected accuracy . Wherein the quality of the geometrical parameters of the fiber optic connector and the end surface morphology affect the accuracy of the connector , when you want to obtain a stable optical fiber system , the optical connector must be very detailed detection , the main test parameters include : three-dimensional morphology radius of curvature , grinding eccentric and fiber height values ??, and the combination of these parameters to give the final evaluation results . In this thesis, the specific area of micron -scale three-dimensional morphology interferometry new methods and new technology , and ultimately achieve the purpose of processing . Comprehensive analysis of a variety of micro-structure measurement methods based on this topic with a Michelson -type interference microscopy system , combined with the phase-shifting phase measurement technique to obtain the morphology of the fiber optic connectors , design and completion of a fiber optic connector The end face of parameter detection interferometer . The main work of this paper include the following aspects: 1 . Determine the the Michelson interferometer detection method this paper . Comprehensive comparison of different light sources , combined with the specific requirements to select the light source of the interference . 3 . Magnification calibration system . . Definition of the parameters of the fiber optic connectors , combined with a related algorithm to get the final results of the evaluation findings . 5 .
