摘要：

This paper presents a general interference formula described the interference pattern of multi-elliptical core optical fibre in a transverse interferometer. This formula with Mach-Zehnder interferometry is used to characterize multi-elliptical core optical fibre via its refractive index measurement. A CCD camera for further automatic processing and analysis captures the interference pattern of the output field of the Mach-Zehnder interferometry by the computer-aided system. This study gives possibility to analyze optical properties and possible optical and geometrical microdefects of multi-core optical fibre. Example of application to identical nine-elliptical core optical fibre of thickness 380 mum fibers is given.
