摘要: A device for measuring the diameter of an object that is generally cylindrical such as, example, optical fiber, without contact. This includes a laser (4) capable emitting luminous beam, means (6, 8, 10) provided to form first and second beams from emitted by illuminate (2) with these beams, so as obtain two reflected which interfere one another, (CCD, 14) photo-detection analysis interference between determining fringes.
