FIBER OPTIC FABRY-PEROT INTERFEROMETER BASED SENSOR FOR INSPECTING CLEAVED FIBER ENDS

摘要

We propose a novel fiber optic sensor for inspecting cleaved optical fiber ends based on Fabry-Perot interferometer. The sensor uses mainly laser diodes, an optical power meter, 3-dB coupler, and XY lateral adjustment fiber stage. Experimentally obtained fiber end images were in good agreement with scanning electron microscope observation images.
