Method for detecting switching status of optical fiber switching unit of fiber-optic measuring device with electromagnetic radiation source and multiple fiber-optic measuring sections, involves activating fiber-optic measuring sections
Device for space-resolved measurement of temperature in optical fibers, has direction-based refraction unit, and evaluation unit determining temperature of optical fiber from detected Rayleigh- and anti-stoke components of scattered light
Object e.g. ski, contact surface and route pavement friction coefficient determining and optimizing method, involves optimizing friction coefficient between surface and pavement so that surface is affected with static/dynamic friction
