Abstract
Photographic method for the measurement of the refractive index profile of optical fibers characterized by the use of photographic negatives of the faces of an optical fiber suitably illuminated by a lambertian light source, an optical focusing system, a microscope device with a photomicrographic camera coupled and densitometric apparatus of the photographic negative.
