Fiber-optic interferometric sensor for monitoring automobile and rail traffic [PDF]
, 2018 This article describes a fiber-optic interferometric sensor and measuring scheme including input-output components for traffic density monitoring. The proposed measuring system is based on the interference in optical fibers. The sensor, based on the Mach-

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...

1986 Solid-State, Actuators, and Microsystems Workshop Technical Digest, 1986 This paper reviews the theory of fiber-optic sensor technology and presents some of the current applications. The future potential for applications of fiber-optic sensors is almost unlimited since there appear to be few parameters that cannot be measured with this technology.

Modulated-splitting-ratio fiber-optic temperature sensor [PDF]
A fiber-optic temperature sensor is described, which uses a small silicon beamsplitter whose splitting ratio varies as a function of temperature. A four-beam technique is used to measure the sensor's temperature-indicating splitting ratio.

Studies on Temperature and Strain Sensitivities of a Few-mode Critical Wavelength Fiber Optic Sensor [PDF]
, 2018 This paper studied the relationship between the temperature/strain wavelength sensitivity of a fiber optic in-line Mach-Zehnder Interferometer (MZI) sensor and the wavelength separation of the measured wavelength to the critical wavelength (CWL) in a CWL-
