Interference effect and digital image processing based on dual-core photonic crystal fiber

摘要

This paper presents the interference effect based on dual-core photonic crystal fiber(PCF)and explains the principle of interference imaging.Interference image of dual-core PCF has been acquired by CCD.Furthermore,digital image processing technique is utilized to extract the skeleton of interference fringes.Eventually,the spacing intervals of interference fringes are obtained successfully by measuring scale calibration.Interference effect based on dual-core PCF paves the way to physical sensing in MEMS field.
