Abstract: In this paper, a fiber optic sensor system (FOSS) is proposed for the measurement of the rotational speed of a DC motor. It offers non-contact measurements. FODS is an intensity modulation based. Radiation absorption excites an orbital electron to a higher energy level. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. A highly precise rotation sensor may be used tomeasure any changes inthe length ofthe day and to detect torsional oscillations inthe earth caused byearthquakes. Fina11y, ultraprecise sensors may find applications in relativity rela experiments ed such as the determination of the preferred frame. This work presents a dynamic rotational sensor using polymethyl methacrylate (PMMA) fiber for robot movement assessment.

Experimental Principle of Fiber Optic Strain Sensor
Fiber optic strain sensors typically function by interpreting changes in light properties as strain is applied. In this paper, accuracy calibration experiments and the related analyses of two fiber-optic sensing technologies, the fiber-optic grating (FBG) and optical frequency domain reflectometry (OFDR), are carried out using a standard beam of equal strength and a mature resistive strain gauge (ESG). Fiber-Bragg-Gratings (FBGs) are used for spot sensing, whereas Rayleigh, Brillouin and Raman scattering are used for distributed sensing in long fibers. A major challenge in the field is to analyze and predict the strain transfer to the fiber core reliably.

Working principle of fiber optic FP sensor
Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. Heating the material enables the trapped states to interact with phonons and decay into lower-energy. A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. It's a device that converts light rays into electronic signals. The principles of FFPI sensors are mainly explained according to Equation 1. When perturbation is introduced to the sensor, the phase difference is influenced with the. Traditional fiber sensors based on different microstructures solely rely on the thermal expansion effect of silica material itself, limiting their usage primarily to temperature or pressure sensing. By employing thin film technology to form Fabry–Perot (FP) cavities on the end-face or inside the. A sensor that uses optical fiber as a detecting element is known as a fiber optic sensor.
