Abstract

Fiber Optic Gyroscope is an optical sensor that can determine the position of the angle of motion of an object. FOG works based on the Sagnac effect, which states that the phase shift between two opposite waves propagates in the interferometry of the rotating ring, and proportional to the angular velocity. Goodness performance indicator of measurement system, is having a small noise. Angle Random Walk is the biggest noise contribution to the error value. In this research, noise estimation from ARW has been done. OFOG performance based on ARW has been described in the ARW simulation based on photon emission and the amount of data sampling per time. The effect of ARW on performance is explained on the PDF graph. Error reduction techniques from ARW values have also been presented to improve OFOG performance. FOG measurement system was developed and experimental results were discussed in this research.
