论文摘要
我们报告了基于双光子布拉格干涉仪中Bloch分离器的检测方案的研究。我们通过选择性将30个Bloch振荡在通过飞行时间检测之前选择性地赋予其中一个Bloch振荡，从而增加干涉仪的两个输出端口之间的空间分离。该方法允许通过减少检测到干涉仪的端口的时间来增加干涉仪的持续时间。我们详细研究了该分离器对双重重力传感器性能的影响，尤其是其对重力加速度和重力梯度的测量敏感性。
We report on the study of a detection scheme based on a Bloch separator in two-photon Bragg interferometers. We increase the spatial separation between the two output ports of the interferometer by selectively imparting 30 Bloch oscillations to one of them before their detection via time of flight. This method allows increasing the duration of the interferometer by reducing the time for discriminating the ports of the interferometer at detection. We study in detail the impact of this separator on the performance of a dual gravity sensor, and in particular on its measurement sensitivities to gravity acceleration and gravity gradients.
