We present a new external off-axis holographic module that doubles the acquired complex wavefront field of view, based on using both holographic flipping and multiplexing. In contrast to previous designs, this design does not require spatial filtering (no pinhole or lenses) to create the reference beam externally. In addition, the overlap area between the fields of view, as well as the off-axis angle between the sample and reference beams, can be fully controlled. As we demonstrate experimentally, this approach is useful for quantitative phase microscopy of extended stationary and dynamic samples, such as cancer cells during rapid flow and beating cardiomyocytes.

翻转干涉仪，成像面积加倍

我们提出了一种新的外部离轴全息模块，该模块在使用全息翻转和复用的基础上使获取的复杂波前视场倍增。与以前的设计相比，此设计不需要空间滤波（无需针孔或透镜）即可在外部创建参考光束。另外，可以完全控制视场之间的重叠区域以及样品和参考光束之间的偏轴角。正如我们通过实验证明的那样，这种方法对于扩展的固定和动态样品（例如快速流动过程中的癌细胞和跳动的心肌细胞）的定量相显微镜检查很有用。
