我们介绍了一种新的单像素成像技术，通过同时获取相同物体的空间频率信息，自动共注册定量相位和非相干图像模式。该技术包括使用时变槽密度衍射光栅产生参考和扫描光束。光束之间的干涉在样品中产生时变的空间频率。在单像素检测器上收集的光产生时间轨迹，可以轻松恢复相干和非相干对比机制。我们推导了定量相的理论，并与实验数据和数值模型非常吻合。此外，我们推导了一个一般理论的单像素定量相位理论，可以广泛应用于一般方法，使用一个序列的调制光模式的单像素相位成像。(C) 2017年Elsevier Inc.出版。
We introduce a new single pixel imaging technique that automatically co-registers quantitative phase and incoherent image modalities through the simultaneous acquisition of identical object spatial frequency information. The technique consists of using a time varying groove density diffraction grating to produce a reference and scan beam. The interference between the beams produce time varying spatial frequencies in the sample. The collected light on a single pixel detector produces a time trace that allows easy recovery of coherent and incoherent contrast mechanisms. We derive theory for the quantitative phase and show excellent agreement with experimental data and numeric model. Additionally, we derive a general theory of single pixel quantitative phase theory that can be applied broadly to general methods that use a sequence of modulated light patterns for single pixel phase imaging.
