Fiber Grating Atmospheric Pressure Sensor Based on Micro-bending Characteristic
This paper proposed a new pressure sensor based on long period fiber grating resonant peak modulation through the LPFG microbending sensitivity characteristics and membrane structure with box. Research results show that: the sensor measurement is in the range of 0~0.25 MPa, the detection resolution is 0.24469 hPa/dB, LPFG resonance spectroscopy changing law and the theoretical derivation, numer...
متن کاملFabry-Perot diaphragm fiber-optic sensor.
The general theory of a diaphragm fiber-optic sensor (DFOS) is proposed. We use a critical test to determine if a DFOS is based on Fabry-Perot interference or intensity modulation. By use of the critical test, this is the first design, to the best of our knowledge, of a purely Fabry-Perot DFOS, fabricated with microelectromechanical system technology, and characterized as an audible microphone ...
متن کاملMicro-air-gap based intrinsic Fabry-Perot interferometric fiber-optic sensor.
A simple intrinsic Fabry-Perot interferometric (IFPI) sensor is developed. The sensor is fabricated by two micro air gaps as reflective mirrors in a fiber to form a Fabry-Perot cavity. Theoretical and experimental studies of the sensor are described. Experimental results show that high resolution and high sensitivity can be achieved. Two structures of micro-air-gap-based IFPI sensors offer more...
متن کاملCompressible fiber optic micro-Fabry-Pérot cavity with ultra-high pressure sensitivity.
We propose and demonstrate a pressure sensor based on a micro air bubble at the end facet of a single mode fiber fusion spliced with a silica tube. When immersed into the liquid such as water, the air bubble essentially acts as a Fabry-Pérot interferometer cavity. Such a cavity can be compressed by the environmental pressure and the sensitivity obtained is >1000 nm/kPa, at least one order of ma...
متن کاملFiber optic extrinsic Fabry-Perot interferometric sensor for high blast pressure measurement
Optical fiber based Extrinsic Fabry-Perot Interferometric (EFPI) sensor significantly emerged as an advanced optical sensor for the health monitoring of civil, mechanical and aeronautical structures. This sensor responds its well capability also towards the measurement of acoustic/shock wave pressure. This paper presents an approach for high blast (acoustic/shock wave) pressure measurement usin...
