Distributed fiber-optic vibration sensors receive extensive investigation and play a significant role in the sensor panorama. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferomet...

Introduction: Fiber optic technology for dissolution testing has been a topic of interest for many researchers for some years. Josefson, Johansson, and Tortensson 1 published early research in this field in 1988. They explored the feasibility of using UV fiber optics for in-situ dissolution and to overcome sample turbidity interference without filtration. In 1993, Brown and Lin 2 used a single ...

A new fiber optic microsensor has been developed for pressure measurement. The pressure microsensor is extremely small (360 micro m). Performance characteristics of the microsensor were evaluated over a pressure range from 0 to 250mmHg. Five sensors were compared to a National Institute of Standards and Technology traceable reference pressure. The microsensor had an accuracy, repeatability, and...

Fiber-optic DNA biosensors are a kind of analytic setups, which convert the Waston-Crick base pairs matching duplex or Hoogsteen’s triplex (T/A-T, C/G-C) formation into a readable analytical signals when functionalized singlestrands DNA (ssDNA) or double-strands DNA (dsDNA) of interest are immobilized on the surface of fiber-optic hybrids with target DNA or interacts with ligands. This review w...

Throughout the fiber optics industry, one is constantly hearing that without substantial improvements in production efficiency, new markets for fiber optic technology will remain elusive. It is therefore a common goal throughout the fiber optics industry to continually improve production processes. We propose a scalable improvement for a production step found in a wide range of fiber optic comp...
