How to measure tilt angle using a fiber optic grating

How to measure tilt angle using a fiber optic grating

Tilt sensors are devices that measure the tilt or slope of an object with respect to a reference. Fibre Bragg Grating (FBG) tilt sensors are a specific type of tilt sensor that utilizes the principle of Bragg's law in fiber optics to measure tilt angles. The tilt sensor is composed of two cylindrical floats suspended in water, connected with FBG. When the external environment causes the tilting of the sensor.
