Fiber optic displacement sensor for determining rotational speed
Abstract: In this paper, a fiber optic sensor system (FOSS) is proposed for the measurement of the rotational speed of a DC motor. CEL s linear sensor has a travel range from less than 1 inch up to 18 inches with an accuracy of 0. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. A device is provided for measuring angular displacement and rotational movement of a shaft or linear displacement of an object comprising a light source, a Multichannel Fiber Optic Bundle, an optical code wheel or linear scale with optical tracks for light modulation, including typically a raster.

Fiber Optic SPR Sensor Structure
Herein, a single-mode optical fiber refractive index sensor based on the SPR is designed and analyzed. Finite element simulations reveal that introducing ITO enhances the surface electric field strength by 1. In recent years, optical fiber–based surface plasmon resonance (SPR) sensors have gained significant attention in biochemical sensing applications due to their high sensitivity, real- time detection capability, and strong selectivity.
