| description | The present invention relates to protecting optical devices, such as an optical fibre sensor connected in series with a cable, from a hostile environment, such as encountered when making measurements in oil and gas wells. A liquid can protect the optical device. Packaging an optical fibre sensor inside a capillary containing the liquid c an provide this protection. The liquid can be liquid metal, gel, inks, grease or oil. The liquid metal can be gallium or indium, or an alloy that includes indium and/or gallium. The grea se can contain lithium, molybdenum, or synthetics, or be synthetic grease. The liquid can contain other components such as a scavenger or getter for molecules and/or ions. |
