查询词典 cavity source

The model of fiber-optic Fabry-Perot interferometer was established when ideal or unideal optical source was applied. Through simulating interferometric signal by computer under the condition of nonmonochromatic light, the symmetry of fringes deteriorated, the fluctuating domain of fringes became small as the ratio of cavity length to coherence length increasing.
