  • OPTICAL SENSING OF MEASURANDS
    Publication number: 20100007892
    Abstract: A dome-shaped chemical sensing probe comprises an optical fiber or may be mounted on an optical fiber. The probe has a chemically sensitive measuring material which exhibits a change in volume and/or a change in refractive index in the presence of a given chemical. The change in volume and/or refractive index gives a change in an optical path length through the probe which can be measured interferometrically.
    Type: Application
    Filed: September 15, 2009
    Publication date: January 14, 2010
    Applicant: Invivosense ASA
    Inventors: Dag R. Hjelme, Arne Berg, Reinold Ellingsen, Berit Falch, Astrid Bjorkoy, Dan Ostling
  • Fabrication of fiber optic probes
    Patent number: 7616844
    Abstract: A method of fabricating a sensor probe comprises: placing the end of an optical fiber 10 in a polymerization space 2; applying a drop of hydrogel pre-gel solution 30 to the end of the fiber; exposing said pre-gel solution to an ultra-violet light source 24 to cause polymerization therein; and monitoring a light signal that has passed down said optical fiber 10 in order to monitor said polymerization.
    Type: Grant
