Express method to obtain the refractive index profile of optical fiber
Abstract
To obtain the refractive index profile of optical fiber, device and method were made. LEDs source were used, and as a photo detector was a microscope combined with a CCD-camera, connected to a PC. Digital image of the output end of fiber was received. Form of refractive index profile can be estimated by using these data.
