  • OPTICAL DEVICE FOR INTERFEROMETRIC ANALYSIS OF THE CONDITION OF THE INTERNAL SURFACE OF A TUBE
    Publication number: 20150124260
    Abstract: The invention relates to an optical device for interferometric analysis of the condition of the internal surface of a tube (11). The device comprises an optical fibre (3), the free end of which is pointed and then bevelled at the single core thereof and the bevelled surface is metalised (10), such that only part of the surface of the fibre core participates in reflecting the incident beam perpendicularly to the axis of the fibre.

  • Use of an optical device for interferometric analysis of the surface condition of an object
    Patent number: 8792104
    Abstract: The instant disclosure describes an optical device for the interferometric analysis of the surface condition of an object, including: a light source; an optical fiber capable of receiving the incident light wave and transmitting said wave to the object; a detector capable of detecting a combination between a light wave reflected by the optical fiber and a light wave returned by the object; and in which the optical fiber has a free end in the shape of a cone, with a vertex angle of between 15 and 25 degrees, the tip of the cone having dimensions of less than 50×50 nm, and the tip of the cone being placed, while in use, at a distance of between 5 and 50 ?m from the surface of the object.
