| 摘 要： | 讨论了球面及平面两种稳频反射镜的加工误差对陀螺腔内光路的偏移作用， 分析了腔内光路随这两种反射镜在稳频平移过程中的变化规律以及光路不对称变形对陀螺朗缪尔零漂的影响。分析结果表明： 无论从稳频反射镜存在加工误差考虑， 还是从稳频平移对陀螺性能影响的考虑， 选择球面镜作稳频反射镜要优于平面镜。

| Abstract: | The displacements of the beam path caused b y the manufacturing errors of concave and flat mirrors for the path length contr ol are discussed. After summarizing the characteristics of variations of the be am path with the normal shift of the mirrors, the effect of an unsymmetrical de formation of the beam path on the drift due to the langmuir flour is evaluated. The analysis demonstrates that it is advantageous to use a concave mirror for t he path length control over a flat one. |
