我们演示了同时相位和振幅成像冷原子使用本征稳定干涉仪基于偏振束置换。这种方法允许通过原子样品传输的光学探针直接检索吸收和相移。此外，我们表明我们的技术具有仅受光子射击噪声限制的信噪比。
We demonstrate simultaneous phase and amplitude imaging of cold atoms using an intrinsically stable interferometer based on polarization beam-displacers. This method allows for the straight-forward retrieval of absorption and phase-shift experienced by an optical probe transmitted through an atomic sample. Furthermore, we show that our technique has a signal-to-noise ratio limited only by photon shot-noise.
