Attenuation of the luminous intensity in the multimode curved optical fiber

The aim of this research is to show that exists an attenuation of the intensity of the luminous wave guided by an optical fiber according to a multitude of parameters as the shape, size and distortions that incur it as for example the curvature. We can use results of this work to achieve an angular optic sensor that permits us to deduct the angular information according to variations of the luminous intensity according to the angle of curvature in the optic fiber constituting this sensor.
