Fiber optic current sensors

  1. Hello seniors..im a undergrad student from hyderabad ,India. Presently im am doing a theory based research project on fiber optic current sensors ..which are mainly used to sense current in substations .

    Recently i got a paper when i googled on the net. It was titled Temperature and Vibration Insensitive Fiber-Optic current sensor(pdf file attached ). In this papers two configurations of FOCS are discussed

    -fiber-optic current sensor with 1.Sagnac interferometer configuration
    2 .Reflective configuration

    As im still graduating ..i dont have a deep knowledge on these configs but howevr im aware of the basics of fiber optics and communications

    Can anyone explain the following :

    1.these two configs in detail...also differences between them ,pricniples of operation,current ratings measured by each..advantages and disadvantages etc

    2.paper explanation in detail..

    Hoping for positive replies...plz help i need this info ASAP
