초록
Sagnac 효과를 사용한 회전센서로 알려진 광자이로스코프(이하 FOG)는 넓은 범위의 회전율을 측정하기 위해 개발 중에 있다. 본 논문은 개루프 FOG의 개발과 FPGA를 이용한 디지털 신호처리 기술을 다루고 있다. 첫째로 Good bias stability(
The interferometric fiber optic gyroscopes (FOGs) are well known as sensors of rotation, which are based on Sagnac effect, and have been under development for a number of years to meet a wide range of performance requirements. This paper describes the development of open-loop FOG and digital signal processing techniques implemented on FPGA. Our primary goal was to obtain intermediate accuracy (pointing grade) with a good bias stability (
