A survey of recent investigations on ocean sensors is carried out with a specific focus on
fiber optic sensing methods, materials for fabricating sensor head and sensor performance …

Chemical equipment has to form a robust and efficient process space and was developed
over the last centuries to very sophisticated, often highly specialized devices. With the …

A humidity and temperature optical fiber sensor based on a long-period grating (LPG), which
can provide simultaneous response to both magnitudes, is proposed and demonstrated via …

A challenge for optical fiber biosensor is to achieve ultrahigh sensitivity with narrow full width
at half maximum (FWHM) of the spectrum. To address this challenge, an ultrahigh-sensitivity …

We propose and develop a high-sensitivity fiber Bragg grating (FBG) accelerometer based
on a flexible hinge for vibration sensing. The proposed method employs a 1-mm FBG that is …

We propose a novel fiber Bragg grating (FBG) accelerometer comprising two straight circular
flexure hinges connected in parallel. The theoretical formulas for the new accelerometer …

A simple method based on Capillary action is proposed to fabricate an optical fiber Fabry-
Perot sensing probe for temperature and humidity measurement. Nafion film serves as the …

In this letter, a temperature sensor based on a fiber ring laser with a reflective Sagnac loop is
proposed. The reflective Sagnac loop inserted into the fiber ring laser through a download …

A compact and simple fiber in-line modal interferometer with an embedded fiber Bragg
grating (FBG) is proposed and experimentally demonstrated for simultaneous measurement …

This work presents a highly stable switchable and tunable erbium-doped fiber laser based
on a Mach-Zehnder interferometer (MZI) made with two symmetrical LPFGs separated by an …
