  • 摘要:

    为了更好地对大口径分段望远镜进行集成检测与稳定性保持基准构建,本文提出一种二八杠棋牌游戏网页版。首先,采用局部光瞳投射的方式实现光瞳对准映射;其次,利用微透镜阵列构建系统共焦空间基准;之后,基于环带整体调控模式,采用共焦与曲率半径联合分析,实现曲率半径与系统对准的共同调节;最后,利用白光干涉所形成的条纹包络进行粗共相探测,并利用通道光谱方法实现粗共相与精共相间的精度衔接,空间共焦基准定位精度优于125 μm,共相基准覆盖范围优于20 μm,精度优于0.5 μm,光谱基准不确定度优于5%。实现了不同时空特征扰动的分层次、多模态抑制,利用以上共基准原位测量新方法有效提升了二八杠棋牌游戏系统原位计量检测精度并缩短了溯源链长度,增加了检测效率与准确度。
