In this study the optical beam transfer and imaging in an optical fiber coupling is discussed. In coupling two fibers, some measurements from intensity perspective are performed and intensity profile is
investigated. A theoretical model for the power transmission in fiber coupling is developed and theoretical function is compared with the experimental results. The amount of light delivered to the receiving fiber depends on the acceptance angle of the receiving fiber and the core cross sections of both fibers. Intensity profile function obtained theoretically agrees well with the measured results. The intensity variation as a function of the air gap variation is investigated in this article. The image of emerging beam of the source fiber is also
investigated. Using captured images one can measure acceptance angle and core diameter of the fiber by using two images of the output beam at two axial distances. The results of this report can be used in optical
communications, data links and image transferring in which single or coupled optical fibers have been used as signal carrier or waveguide.
