研究目的
To inform readers with a keen interest in the detection of metal ion water contaminants, who are not experts in fiber optics on the fundamentals and current state of art of metal ion detections using optical fiber refractometer technologies.
研究成果
The versatility of optical fiber refractometers enabled applications for detection of various heavy metal ions with appropriate choices of surface coating. The operating principles of these sensors are remarkably simple. At the same time, due to the maturity of both optical fiber RI sensing and surface coating technology, these sensors that were proposed have great potential to be translated into affordable commercial products.
研究不足
The limitations still faced by the reported sensors such as selectivity of analyte, cross sensitivity to environmental physical attributes (i.e., temperature and pressure changes), and requirement for bulky interrogation systems.
