Abstract
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 (
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(
