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.

Optical fiber sensor-based inertial measurement system

A sensor assembly has a flexible body, and a plurality of fiber Bragg gratings (FBG) sensor inserted into the body, the FBG sensor includes an optical fiber extending in a length direction of the body and a plurality of lattices disposed in the optical fiber, a variation of a wavelength spectrum of light, caused by a variation of an interval of the plurality of lattices, is detected, and at least one of force information applied to the body and temperature information of the body is extracted together with refraction information of the body.

Multi-functional sensor assembly

A probe sensor has a probe structure having a probe body inserted into an experiment subject, a block body disposed on the probe body to transmit or reflect an incident light, and a light irradiation body for inputting a first incident light to the block body; a first light source for generating the first incident light and transmitting to the light irradiation body; and a light analyzer for analyzing a first reflection light which is a reflection light of the first incident light reflected by the block body, wherein the length of the block body changes according to a temperature change, and wherein the light analyzer measures a temperature change of the experiment subject by detecting a wavelength change of the first reflection light according to the length change of the block body.
