Abstract

 Fiber-optic sensing techniques have received a considerable interest in recent years. Optical fibers have several desired and advantageous attributes useful for sensor applications, including their ability to act as both sensing and information transmitting media. One of the specific aims of this paper is to build an optical system having the capability to measure the attenuation in optical fibers due to its macrobending, and compare (or calibrate) our results with other who used different systems in order to ensure that our system is suitable to use. The attenuation due to bending loss in optical-fiber at different bending radii of fiber, at different multiple circular Joops bending of liber, and at different optical frequencies transmitted through fiber, are insured experimentally by our optical system. The results for these measurements show that the attenuation (or bending loss) increases with decreasing the bonding radius, with increasing number of fiber turns and with increasing transmitted signal frequencies through the bended fiber. This optical system can be used as a sensitive sensor to measure the cracks in steel structures and buildings.
