Abstract
The measurement of rotation is of considerable interest in a number of areas. It is not only used in aircraft but also in new application fields such as automobile navigation, antenna/camera stabilizer, crane control, unmanned vehicle control. The FOG with scanning phase-shift based on anti-noise filter circuit and improved DSP-software algorithm, and the FOG using scanning phase-shift modulation are presented in the paper. The results of experiment show that the proposed FOG is insensitive to interference intensity and changes of light contrast, the stability of FOG is improved greatly
