OPTICAL FIBER SENSOR-BASED INERTIAL MEASUREMENT SYSTEM

Embodiments relate to an Inertia Measurement Unit (IMU) sensor that generates strain information including a change in strain based on first output light of a first type of optical fiber sensing unit, calculates acceleration information of an object on which an IMU sensor () is mounted based on the strain information, generates angular velocity information based on output light of a second type of optical fiber sensing unit, and calculates angle information of the object based on the rotational speed information.
