摘要：

利用未检测到的光子进行感测允许访问光谱区域，同时检测另一区域的光子，并且基于非线性干涉测量。为了获得样品的全部信息，必须在振幅和相位方面分析相应的干涉图，迄今为止，这已经通过多次测量以及随后的相位变化来实现。在这里，我们提出了一种基于偏振光学的相位正交实现在非线性干涉仪与未检测到的光子在红外区域的成像。这使我们能够获得相位和能见度与一个单一的图像采集，而不需要改变光路或相位，从而使动态过程的检测。我们证明了我们的方法的有用性上的静态相位掩模不透明的检测到的光子，以及在动态测量任务作为干燥的异丙醇膜和拉伸的胶带。

英文摘要：

Sensing with undetected photons allows access to spectral regions with simultaneous detection of photons of another region and is based on nonlinear interferometry. To obtain the full information of a sample, the corresponding interferogram has to be analyzed in terms of amplitude and phase, which has been realized so far by multiple measurements followed by phase variation. Here, we present a polarization-optics-based phase-quadrature implementation in a nonlinear interferometer for imaging with undetected photons in the infrared region. This allows us to obtain phase and visibility with a single image acquisition without the need of varying optical paths or phases, thus enabling the detection of dynamic processes. We demonstrate the usefullness of our method on a static phase mask opaque to the detected photons as well as on dynamic measurement tasks as the drying of an isopropanol film and the stretching of an adhesive tape.
