Rotational speed detection based on fiber optic sensor
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. A birefringement optic fiber is connected to a light source, and passes through the magnetic field.

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.

Fiber optic sensor for weld seam inspection
– Laser-profile or optical triangulation sensors are commonly used for weld seam finding because they can generate precise profiles of the weld joint. – Accurate detection of seam position, gap, mismatch, and misalignment ensures high-quality welding with fewer errors. After the welding process has been completed, the result must be checked. Irregularities such as missing, double, undulated or other faulty welds are reliably detected by 2D/3D. SeamControl is the advanced sensor system for optical laser weld seam inspection - based on the proven technology of the SOUVIS system and consistently further developed to meet the requirements of modern, networked production environments. This has a positive effect on productivity, as it allows for a faster production project. Active seam detection scans the edge offset at the joint without contact using light bars, thus ensuring precise positioning of the tool at all times. Click on each standard to learn more.
