DESIGN AND FABRICATION OF A NON CONTACT VERSATILE RANGE FORCE SENSOR

Fiber Optic Sensor Design and Fabrication Methods

This Special Issue focuses on the innovative design of optical fiber sensor structures, including fiber Bragg gratings, long-period gratings, interferometric sensors, and advanced micro-structured fibers. Optical fiber sensors are devices that use optical fibers to detect and measure various parameters such as temperature, pressure, strain, and refractive index. The apparatus includes a heating source (110) and a robotic articulate arm (130) that may modify the geometry of an optical fiber (150). Nowadays fiber optic refractive index sensors are widely used in various fields such as chemical, biochemical, and in an industry field. The optical fibre can be used as a distributed sensor by exploiting light scattering effects or as a quasi-distributed sensor network by functionalizing the fibre through Bragg gratings photo-inscription for instance.

Fiber Optic Temperature Sensor Fabrication Method

We demonstrate the fabrication of fiber-optic Fabry-Perot interferometer (FPI) temperature sensors by bonding a small silicon diaphragm to the tip of an optical fiber using low melting point glass powders heated by a 980 nm laser on an aerogel substrate. Besides, they exhibit high measurement speeds and high sensitivity due to the large thermal diffusivity and the large thermo-optic coefficient of silicon and the small size of the sensing element. Fiber Bragg gratings are very efficient at temperature sensing and are easy to implement; however, they always need additional techniques to discriminate the Bragg shifts by temperature and by strain/compression and they also require expensive phase-masks.

Fiber Optic Counting Liquid Level Sensor

This technology, known as WLPI (White Light Polarization Interferometry), operates using the phase modulation of light — the most sensitive method for fiber-optic measurements. Hydrostatic pressure measurement with optical sensors enables precise long-term monitoring of liquid. In this paper, a novel liquid level sensing system is proposed to enhance the capacity of the sensing system, as well as reduce the cost and increase the sensing accuracy.

Can the sensing distance of a fiber optic sensor be adjusted

Optical fibers can be made into interferometric sensors such as fiber-optic gyroscopes, which are used in the Boeing 767 and in some car models (for navigation purposes). It is well-known the propagation of light in optical fiber is confined in the core of the fiber based on the total internal reflection (TIR) principle and near-zero propagation loss within the cladding, which is very important f.
