Slow-Light Fiber-Bragg-Grating Strain Sensor With a 280- Resolution
Fiber Bragg gratings fi ber optics sensors
2015/8/7
We report a fiber strain sensor based on a single fiber Bragg grating (FBG) with a minimum detectable strain of 280 in the 20-kHz range. This breakthrough was made possible by operating th...
Highly sensitive fiber loop ringdown strain sensor using photonic crystal fiber interferometer
Highly sensitive fiber loop ringdown strain sensor photonic crystal fiber interferometer
2013/5/27
A highly sensitive strain sensor is demonstrated by introducing a photonic crystal fiber (PCF) Mach–Zehnder interferometer (MZI) in a cavity ringdown fiber loop as a sensing element. The MZI is fabric...
Strain Sensor Realized by Using Low-Birefringence Photonic-Crystal-Fiber-Based Sagnac Loop
Fiber Sagnac loop optical fiber sensor photonic crystal fiber (PCF) strain sensor
2013/5/27
An optical fiber strain sensor by using a low-birefrin-gence photonic crystal fiber (PCF)-based Sagnac loop is demon-strated. A fiber Sagnac loop is formed by the low-birefringence PCF of about 40 cm,...
Intensity measurement based temperature-independent strain sensor using a highly birefringent photonic crystal fiber loop mirror.
Highly birefringent photonic crystal fiber (HiBi-PCF) Fiber loop mirror (FLM) Strain senor Intensity measurement
2013/5/27
A fi ber-optic strain sensor is demons trated by using a short length of highly birefringent phot onic crystal fi ber (HiBi-PCF) as the sensing element inserted in a fi ber loop mirror (FLM). Due to t...
FBG STRAIN SENSOR WITH SIMPLE TEMPERATURE COMPENSATION MECHANISM
FBG sensor strain measurement temperature compensation
2008/12/25
A FBG-based strain sensor equipped with a mechanical temperature compensation system is proposed. Direct bonding of a FBG element may cause broadening of the reflected optical spectrum due to fluctua...
