Abstract

An apparatus and method of embedding an optical fiber within a substrate. The apparatus includes a bonding device and a conveyance device. The bonding device bonds a foil layer to the substrate to seal the optical fiber within a groove of the substrate. The conveyance device moves the substrate and the bonding device relative to each other. Relative motion between the substrate and the bonding device draws the optical fiber into the groove and the foil layer over the optical fiber at a collection point.

First claim

What is claimed is:

1. An apparatus for embedding an optical fiber in a groove formed within a substrate, comprising:
a housing configured to move with respect to the substrate along a direction of the groove;
a fiber spool in the housing, the fiber spool having an optical fiber wound thereon;
a foil spool in the housing, the foil spool having metal foil wound thereon; and
an ultrasonic bonding device in the housing that generates ultrasonic waves for bonding metal,
wherein movement of the housing with respect to the substrate draws the optical fiber into the groove and the metal foil over the optical fiber at a collection point to form a chamber that houses the optical fiber and subsequently moves the ultrasonic bonding device over the metal foil to bond the metal foil to the substrate.

2. The apparatus of claim 1 , wherein the substrate is one of: (i) a metal strip; (ii) a tubular; (iii) a pipe; (iv) a containment vessel; (v) a member used in fluid sequestration; (vi) a member used in CO 2 sequestration; and (vii) a member used in hydrogen sequestration.

3. The apparatus of claim 1 , wherein the substrate is stationary and the ultrasonic bonding device is in motion relative to the substrate.
