Corrosion-induced optical fiber microbending is demonstrated within this article as an efficient method for the design of sensors for the detection and localization of corrosion events on monitored metal surfaces. The proposed sensors were demonstrated in a single point and Read More …
This Letter describes a miniature Fabry–Perot, contactless, magneto-optic sensor for angular position measurement. The sensor utilizes a magneto-optic fluid comprising barium hexaferrite nanoplatelets that become birefringent in the presence of an external magnetic field and a compact fiber-optic sensor system Read More …
This paper presents a miniature, all-silica, flow-injection sensor. The sensor consists of an optical fiber-coupled microcell for spectral absorption measurements and a microfluidic reagent injection system. The proposed sensor operates in back reflection mode and, with its compact dimensions, (no Read More …
This paper presents a short response time, all-silica, gas-flow-velocity sensor. The active section of the sensor consists of a 16 µm diameter, highly optically absorbing micro-wire, which is heated remotely by a 980 nm light source. The heated microwire forms Read More …
This paper presents a miniature fiber-optic Pitot tube for gas flow rate measurements created at the tip of an optical fiber. The proposed all-fiber sensor employs two in-fiber Fabry-Perot cavities/chambers. The first chamber is arranged as a differential pressure sensor Read More …
In this paper, an optical fiber sensor is proposed for measurement of the boiling point and boiling range of liquids. Since boiling point and/or boiling range of liquids correlate directly to chemical composition of liquids, the proposed sensor provides opportunity Read More …
A miniature all-fiber Fabry–Perot sensor for measurement of force is presented in this Letter. The sensor consists of a thin silica diaphragm created at the tip of the fiber. The central part of the diaphragm is extended into a silica Read More …
This paper proposes an all-optical-fiber sensor for continuous measurements of liquid levels. The proposed sensor utilizes an optically absorbing vanadium doped optical fiber, which is configured as a long-gauge, optically-heated, fiber-optic, Fabry-Perot interferometer that is immersed into the measured liquid. Read More …
A combination of focused ion beam milling and chemical etching is proposed for the creation of Fabry-Perot cavities in microwires. Both simple cavities and cantilevers are created on 15 ?m-diameter microwires and characterized in temperature. The cantilever structure shows sensitivity Read More …
A system for accurate balancing and controlled unbalancing of the optical path difference in all-fiber optical interferometers is described. Interferometers with various arm lengths (1-30 m) and with initial optical path differences of as much as 1 cm have been Read More …
