Abstract
An automatic machine for welding optical fibers end-to-end comprises a first plate (1) for supporting a first or 'reference' fiber (2) and a second plate (5) for supporting a second or 'moving' fiber (6). The second plate can be translated along Ox and Oy axes in a plane perpendicular to the axes of the fibers. The ends of the fibers are illuminated by light sources (30, 31), optical systems make images thereof, and optical pick-ups (12, 13, 18, 19) located at the image points provide optical signals representative of the positions of the optical fibers relative to each of said Ox and Oy axes. These signals are converted into electrical signals and are compared by electronic comparators (15, 21) which deliver corresponding error signals to control means (17, 23, 24) for moving the second plate until the moving fiber is in alignment with the reference fiber.
