Abstract
In this paper, we carried out the performance evaluation of depolarized fiber optic gyroscope(D-FOG) that was designed and fabricated with the low-cost optical communication single mode fiber and depolarizer. In order to reduce the phase error of D-FOG, the circuit of stabilized current and temperature of the light source was made and the performance was analyzed. The current and the temperature stability of the fabricated stabilization circuit were less than
본 논문에서는 저가의 광통신용 단일모드 광섬유와 편광소멸기를 이용한 비편광 광섬유 자이로스코프(D-FOG)를 설계/제작하여, 성능을 평가하였다. D-FOG의 위상오차를 줄이기 위해 사용광원의 전류 및 온도 안정화 회로를 제작하여 그 성능을 분석하였다. 제작된 전류 및 온도 안정화 회로의 전류 안정도는
