An Adaptive Damping Network Designed for Strapdown Fiber Optic Gyrocompass System for Ships
The strapdown fiber optic gyrocompass (strapdown FOGC) system for ships primarily works on external horizontal damping and undamping statuses. When there are large sea condition changes, the system will switch frequently between the external horizontal damping status and the undamping status. This means that the system is always in an adjustment status and influences the dynamic accuracy of the...
متن کاملFiber-Optic Chemical Sensors and Fiber-Optic Bio-Sensors
This review summarizes principles and current stage of development of fiber-optic chemical sensors (FOCS) and biosensors (FOBS). Fiber optic sensor (FOS) systems use the ability of optical fibers (OF) to guide the light in the spectral range from ultraviolet (UV) (180 nm) up to middle infrared (IR) (10 μm) and modulation of guided light by the parameters of the surrounding environment of the OF...
متن کاملFiber - Optic Sensing of Linear Thermal Expansion (RESEARCH NOTES)
The use of a LED fiber-optic sensor to measure displacement and linear thermal expansion is described. It has a sensitivity of about 0.6 mV/mm, a resolution of 1.25 mm, and a dynamic rang of 400 mm for displacement measurements. For thermal expansion, it shows a sensitivity of about 3.5 mV/C, and the experimental linear expansion values are in agreement with those calculated. The reported senso...
متن کاملA fiber optic sensor for measuring glucose in aqueous solutions
In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...
متن کاملFiber-Optic Sensing Technologies
The fiber optics and optoelectronics industry has experienced a tremendous amount of innovation over the past four decades. Initially conceived for medical endoscopic applications, optical fibers were considered in the mid-1960s as an adequate technology for telecommunications applications. Since then, light wave communications systems have become the preferred and standard method to transmit v...
