Abstract

We use Einstein synchronization formalism to investigate and compare the general relativistic corrections of the Sagnac effect for an Earth-Fixed rotating observer in flat, Newtonian, Schwarzschild, and weak-Kerr backgrounds. This comparison shows that the correction due to the Earth’s angular momentum, which is only achieved in the weak-Kerr background, is equal in order of magnitude to the correction due to the Earth’s mass and larger than the correction due to the angular velocity of the rotating frame. The phase shift resulting from this time correction is measurable and therefore its consideration is of experimental importance.

固定地球旋转观测者框架中的萨格纳克效应：比较研究

我们使用爱因斯坦同步形式来研究和比较固定地球的旋转观测者在平面、牛顿、史瓦西和弱克尔背景下的Sagnac效应的广义相对论修正。这一对比表明，只有在弱克尔背景下，由地球角动量引起的校正与由地球质量引起的校正在数量级上是相等的，并且大于由旋转框架的角速度引起的校正。这种时间校正引起的相移是可测量的，因此对它的考虑在实验中具有重要意义。
