Abstract
A device for aligning a light beam with an optical fiber in order to introduce the beam into the fiber. The device includes a sample-taking device to sample part of the light beam which falls along the periphery of a circle which has a center on the axis of the fiber. The sampled light is then detected in order to analyze the angular distribution of the corresponding light intensity. The angular distribution becomes uniform when the axis of the light beam coincides with the axis of the optical fiber.
