Interferometric Fiber Optic Sensors
Fiber optic interferometers to sense various physical parameters including temperature, strain, pressure, and refractive index have been widely investigated. They can be categorized into four types: Fabry-Perot, Mach-Zehnder, Michelson, and Sagnac. In this paper, each type of interferometric sensor is reviewed in terms of operating principles, fabrication methods, and application fields. Some s...
متن کاملFiber Optic Interferometric Devices
Fiber optic interferometry can be broadly explained as the techniques that utilize the fundamental principles of optical interference to measure physical sample properties or detect changes via sensing systems that are partially or completely realized using fiber optic components. While the field of optical interference dates back to second half of seventeenth century, the advent of fiber optic...
متن کاملCoherence Multiplexing of Fiber-optic Interferometric Sensors
This paper describes a method of multiplexing several optical signals onto a single spatial channel (e.g., a single-mode fiber) using a short coherence length continuous wave light source. Several system configurations which utilize this technique are proposed, and some design considerations are discussed. Experimental results for a single sensor and receiver are presented and compared with the...
متن کاملOptoacoustic imaging using fiber-optic interferometric sensors.
An interferometric sensor based on nonmetallic silica optical fiber is presented as an ultrasonic wideband transducer for optoacoustic imaging applications. We have characterized the sensitivity of the optical fiber sensor by detecting optoacoustic signals from an optically absorbing object embedded in a tissue-mimicking phantom and have compared the signals recorded with those detected from th...
متن کاملMiniaturized fiber-optic Michelson-type interferometric sensors.
We present a novel, miniaturized Michelson-type fiber-optic interferometric sensor that is relatively insensitive to temperature drifts. A fused-biconical tapered coupler is cleaved immediately after the coupled length and polished down to the region of the fused cladding, but short of the interaction region. The end of one core is selectively coated with a reflective surface and is used as the...
