چکیده
We present a study of simultaneous detection curvature and strain in optical fiber. This contains micro tapered section nano section. The transmission spectrum shows interference multiple modes, the frequency modulation can be used to distinguish monitor specific physical parts fiber structure. is achieved using one component; this component an intensity with sensitivity 0.26 dB/m?1. information extracted by applying phase analysis over second spatial close 8 mrad/??. exhibits linear response, data indicates exponential model. proposed signal employed for interferometric sensors.

Tapered Optical Fiber Coated with ZnO Nanorods for Detection of Ethanol Concentration in Water
This work presents ZnO nanorods coated multimode optical fiber sensing behavior in response to ethanol solution. The sensor operates based on modulation of light intensity which arises from manipulation of light interaction with the ambient environment in sensing region. For this purpose, two steps are experimentally applied here; etching and then coating fiber with ZnO nanorods to provide stro...
متن کاملTapered Optical Fiber Sensor for Label-Free Detection of Biomolecules
This paper presents a fast, highly sensitive and low-cost tapered optical fiber biosensor that enables the label-free detection of biomolecules. The sensor takes advantage of the interference effect between the fiber's first two propagation modes along the taper waist region. The biomolecules bonded on the taper surface were determined by demodulating the transmission spectrum phase shift. Beca...

15 صفحه اولAdaptable Optical Fiber Displacement-Curvature Sensor Based on a Modal Michelson Interferometer with a Tapered Single Mode Fiber
A compact, highly sensitive optical fiber displacement and curvature radius sensor is presented. The device consists of an adiabatic bi-conical fused fiber taper spliced to a single-mode fiber (SMF) segment with a flat face end. The bi-conical taper structure acts as a modal coupling device between core and cladding modes for the SMF segment. When the bi-conical taper is bent by an axial displa...
متن کاملSimultaneous Temperature and Strain Sensing for Cryogenic Applications Using Dual-Wavelength Fiber Bragg Gratings
A new technique has been developed for sensing both temperature and strain simultaneously by using dual-wavelength fiber-optic Bragg gratings. Two Bragg gratings with different wavelengths were inscribed at the same location in an optical fiber to form a sensor. By measuring the wavelength shifts that resulted from the fiber being subjected to different temperatures and strains, the wavelength-...
