New Opportunities in Fiber-optic Sensors
نویسنده
چکیده
Several possibilities for new fiber-optic sensors are proposed that are based on two-photon spectroscopic techniques. Examples are chemical sensors, including multiplexed sensors, as well as magnetidelectric sensors. The development of a compact, low-cost fiber-optic method for tbe accurate measurement of timdfrequency is also proposed.

COMPARISON OF DIFFERENT GLASS COMPOUNDS FOR INTRINSIC FIBER OPTIC TEMPERATURE SENSORS
Different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. The phase changes for eight different glass materials were calculated and results were compared. Our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. In another study the effect of wavelength on the phase variatio...

متن کاملResearch on Fiber Optic Sensor based on Fuzzy Control Theory
Fiber optic sensors can be used to monitor deformation and/or the overall integrity of structure components. In this paper, we propose a fuzzy control theory based control principle for sensors, and design a new kind of fiber optic sensor used for Geological monitoring. In order to validate the efficiency of the designed sensor, we simulate a water inrush model in a coal mine, and observe the w...
متن کاملPlasmonic Fiber Optic Refractometric Sensors: From Conventional Architectures to Recent Design Trends
Surface Plasmon Resonance (SPR) fiber sensor research has grown since the first demonstration over 20 year ago into a rich and diverse field with a wide range of optical fiber architectures, plasmonic coatings, and excitation and interrogation methods. Yet, the large diversity of SPR fiber sensor designs has made it difficult to understand the advantages of each approach. Here, we review SPR fi...
