Abstract
A measurement system, a measurement device, and a measurement method being able to measure a flow speed for each position of an optical fiber are provided. According to one example embodiment, a measurement system includes: an object provided in a fluid, and generating a self-excited vibration by the fluid; an optical fiber provided in the fluid, and detecting the vibration; a light source outputting light P to the optical fiber; an acquisition unit acquiring backscattered light generated from the light P in the optical fiber and including a pattern indicating the vibration in a vibration position on the optical fiber to which the vibration of the fluid is transmitted; and a measurement unit measuring, from a pattern included in the backscattered light and indicating the vibration, a flow speed of the fluid in the vibration position.
