OPTICAL SENSORS AND THEIR APPLICATIONS
[attachment=50152]
INTRODUCTION
NEW REVOLUTION OF OPTICAL FIBER SENSORS
IT IS A “SPIN-OFF” FROM OTHER OPTICAL TECHNOLOGIES
SEEING THE POTENTIAL IN SENSING APPLICATIONS – DEVELOPED AS ITS OWN FIELD
WHY OPTICAL SENSORS
ELECTROMAGNETIC IMMUNITY
ELECTRICAL ISOLATION
COMPACT AND LIGHT
BOTH POINT AND DISTRIBUTED CONFIGURATION
WIDE DYNAMIC RANGE
AMENABLE TO MULTIPLEXING
WORKING PRINCIPLE
LIGHT BEAM CHANGES BY THE PHENOMENA THAT IS BEING MEASURED
LIGHT MAY CHANGE IN ITS FIVE OPTICAL PROPERTIES i.e INTENSITY, PHASE, POLARIZATION,WAVELENGTH AND SPECTRAL DISTRIBUTION
PARTIAL DISCHARGE DETECTION USES OPTICAL FIBER SENSORS
OPTICAL FIBER SENSORS ARE BEING TESTED FOR USE IN DETECTING PARTIAL DISCHARGES IN ELECTRICAL TRANSFORMERS. PINPOINTING SUCH DISCHARGES IS ESSENTIAL TO PREVENTING INSULATION BREAKDOWN AND CATASTROPHIC FAILURES.
CONCLUSIONS
LOOKING AT THE INDUSTRY TRENDS IN THE PAST 2 DECADES AND THE EXPONENTIAL CURVE IT SEEMS TO ME THAT THERE IS GOING TO BE A LOT OF RESEARCH AND IMPROVEMENTS TO THE EXISTING SENSORS
OPTICAL SENSORS ARE HERE TO STAY !!!!
